Steroids 164-171 serpin family A member 6 Homo sapiens 209-212 8031716-3 1994 Analyses of the resulting mutants indicate that Trp371 is most likely located in the steroid-binding site, and that hydrophobic interactions between Trp141 and the steroid molecule or other amino-acids in the CBG polypeptide may also contribute to high-affinity interactions between CBG and its steroid ligands. Steroids 164-171 serpin family A member 6 Homo sapiens 209-212 8180202-9 1994 This suggests that interaction between this carbohydrate chain and the polypeptide is necessary for the folding and creation of the steroid-binding site only during CBG biosynthesis.

Steroids 38-45 serpin family A member 6 Homo sapiens 68-99 1430842-1 1992 The abnormal concentrations of steroid hormones and free fatty acids in the plasma of HIV-infected subjects are associated with qualitative and quantitative alterations in two of the major steroid hormones carrier proteins, sex steroid-binding protein (SBP) and corticosteroid-binding globulin (CBG). Steroids 31-47 serpin family A member 6 Homo sapiens 262-293 8268315-0 1993 [The effect of steroids on binding of transcortin with human syncytiotrophoblasts]. Steroids 15-23 serpin family A member 6 Homo sapiens 38-49 8268315-2 1993 It was shown that native CBG variants stripped of steroids lose their ability to interact with specific membrane sites. Steroids 50-58 serpin family A member 6 Homo sapiens 25-28 8318949-3 1993 The excellent agreement (r = 0.98) seen between the present study and a binding assay indicates that the polyclonal antibodies used recognize only intact steroid-binding CBG. Steroids 154-161 serpin family A member 6 Homo sapiens 170-173 1430842-1 1992 The abnormal concentrations of steroid hormones and free fatty acids in the plasma of HIV-infected subjects are associated with qualitative and quantitative alterations in two of the major steroid hormones carrier proteins, sex steroid-binding protein (SBP) and corticosteroid-binding globulin (CBG). Steroids 31-47 serpin family A member 6 Homo sapiens 295-298 1862072-2 1991 To map the steroid-binding domain and to investigate the folding pathways of hCBG, we have established an expression system based on infection of insect cells with a recombinant baculovirus encoding hCBG. Steroids 11-18 serpin family A member 6 Homo sapiens 199-203 1504007-5 1992 To assess the impact of each substitution on the steroid binding affinity of CBG, each mutation was introduced separately into a normal human CBG cDNA, and the normal and mutated cDNAs were expressed in Chinese hamster ovary cells. Steroids 49-56 serpin family A member 6 Homo sapiens 77-80 1504007-7 1992 We therefore conclude that residue 93 may play an important role in determining the structure of the CBG steroid binding site. Steroids 105-112 serpin family A member 6 Homo sapiens 101-104 1620285-7 1992 Very probably, pathological production or excessive dosage of steroids that are negligibly bound to SHBG or CBG will produce CSF and brain levels in the near micromolar range. Steroids 62-70 serpin family A member 6 Homo sapiens 108-111 1778174-1 1991 Two steroid-binding proteins circulate in plasma, corticosteroid-binding globulin and sex hormone-binding globulin. Steroids 4-11 serpin family A member 6 Homo sapiens 50-81 1778174-8 1991 There are, as yet, no published reports on the control of CBG binding by steroids. Steroids 73-81 serpin family A member 6 Homo sapiens 58-61 1778174-9 1991 For both SHBG and CBG, if an appropriate steroid is present when the binding protein is itself bound to its receptor, rapid induction of adenylate cyclase activity and the accumulation of intracellular cAMP occur. Steroids 41-48 serpin family A member 6 Homo sapiens 18-21 1783881-1 1991 Earlier views indicated that globulin (corticosteroid-binding globulin (CBG) or sex hormone-binding globulin (SBG)) but not albumin binding in plasma, protects steroids from splanchnic metabolism in man.

Steroids 160-168 serpin family A member 6 Homo sapiens 72-75 1783881-6 1991 The "complex", probably most realistic, model includes 13 steroids, which can simultaneously bind to plasma albumin, CBG and SBG. Steroids 58-66 serpin family A member 6 Homo sapiens 117-120 1862072-7 1991 Comparison of the steroid-binding properties of intracellular and secreted hCBG with that synthesized in vitro in the rabbit reticulocyte lysate system suggests that this protein undergoes a maturation process during transport through the secretory pathway. Steroids 18-25 serpin family A member 6 Homo sapiens 75-79 1659892-7 1991 Collectively, these findings suggest that both normal CBG and pCBG are involved in the guided transport of steroid hormones to the target cells and transmembrane transfer of hormones and/or hormonal signals. Steroids 107-123 serpin family A member 6 Homo sapiens 54-57 1646610-3 1991 We assume that this protein is a component of membrane recognition system for transcortin-steroid complexes. Steroids 90-97 serpin family A member 6 Homo sapiens 78-89 1822399-2 1991 It is now not only demonstrated that this plasma glycoprotein, a steroid carrier, can be internalized by glucocorticoid target tissues, but it is also certain that CBG mRNA is synthesized by extra-hepatic tissues. Steroids 65-72 serpin family A member 6 Homo sapiens 164-167 1958574-1 1991 Phylogenetic comparisons of the primary structure of corticosteroid binding globulin (CBG) have revealed several conserved domains that include sites for N-glycosylation and a region which probably represents a portion of the steroid binding site. Steroids 60-67 serpin family A member 6 Homo sapiens 86-89 2268356-4 1990 This suggests that transcortin-cortisol complex penetrates the plasma membrane and the transcortin-bound steroid can thus enter syncytiotrophoblast and exert its hormonal effects on this tissue. Steroids 105-112 serpin family A member 6 Homo sapiens 19-30 2268356-4 1990 This suggests that transcortin-cortisol complex penetrates the plasma membrane and the transcortin-bound steroid can thus enter syncytiotrophoblast and exert its hormonal effects on this tissue.

Steroids 40-47 serpin family A member 6 Homo sapiens 0-11 2765544-3 1989 Transcortin binding to the membrane was steroid-dependent: transcortin-cortisol complex bound to the membranes substantially more weakly than transcortin-progesterone, and specific binding of transcortin devoid of steroid was not detected.

Steroids 135-143 serpin family A member 6 Homo sapiens 88-91 3135173-1 1988 The steroid hormones, progesterone (P4) and cortisol (F), have different biological activities but are both bound to human corticosteroid binding globulin (CBG) with similar affinity. Steroids 4-11 serpin family A member 6 Homo sapiens 123-154 3135173-1 1988 The steroid hormones, progesterone (P4) and cortisol (F), have different biological activities but are both bound to human corticosteroid binding globulin (CBG) with similar affinity. Steroids 4-11 serpin family A member 6 Homo sapiens 156-159 3135173-4 1988 Unsaturated fatty acids (UFA) had a dose-dependent inhibitory effect (P less than 0.001) on steroid binding to CBG which was offset by saturated fatty acid-induced potentiation of binding (P less than 0.01) when both were present with CBG. Steroids 92-99 serpin family A member 6 Homo sapiens 111-114 3135173-8 1988 Scatchard analysis of steroid binding to purified CBG indicated that the UFAs influenced the association constant (Ka) and the number of binding sites (n) for F and P4 binding differently. Steroids 22-29 serpin family A member 6 Homo sapiens 50-53 3379127-17 1988 However, small fractions of the respective steroids are bound to transcortin and albumin. Steroids 43-51 serpin family A member 6 Homo sapiens 65-76 3125170-7 1988 This was in contrast to the results obtained with 3,20-18O-labeled progesterone and partially purified transcortin, where a complete loss of 18O label in the protein-bound steroid was found. Steroids 172-179 serpin family A member 6 Homo sapiens 103-114 2839166-1 1988 Corticosteroid-Binding globulin (CBG) is a plasma protein that binds certain steroid hormones, mainly cortisol and progesterone. Steroids 77-93 serpin family A member 6 Homo sapiens 0-31 2839166-1 1988 Corticosteroid-Binding globulin (CBG) is a plasma protein that binds certain steroid hormones, mainly cortisol and progesterone. Steroids 77-93 serpin family A member 6 Homo sapiens 33-36 2839166-4 1988 These events are critically dependent upon a steroid being bound to CBG. Steroids 45-52 serpin family A member 6 Homo sapiens 68-71 2967419-5 1988 The heritability index for variability of the plasma content of steroids was 45.4% (p less than .05) for total cortisol, 50.6% (P less than .05) for unbound plasma cortisol, 57.8% (P less than .05) for DHEA-S, and 32.4% (P greater than .05) for CBG. Steroids 64-72 serpin family A member 6 Homo sapiens 245-248 3125170-9 1988 These results indicate a participation of steroid oxo groups in the binding of progesterone to transcortin. Steroids 42-49 serpin family A member 6 Homo sapiens 95-106 3125170-10 1988 Of the possible mechanisms discussed, imine bonds between the steroid and transcortin seem most likely although other types of interactions cannot be ruled out. Steroids 62-69 serpin family A member 6 Homo sapiens 74-85 3732369-8 1986 The disposition rate of these two steroids is thus similar, in spite of their metabolic control by different enzymatic pathways and major influence of saturable transcortin binding on prednisolone elimination. Steroids 34-42 serpin family A member 6 Homo sapiens 161-172 3056181-12 1988 At this time, we believe that CBG"s hormonal role is compatible with a hypothesis that encompasses the view that unbound steroid hormones can diffuse into cells in some tissues and that both free and bound steroid can enter cells in others. Steroids 121-137 serpin family A member 6 Homo sapiens 30-33 3056181-12 1988 At this time, we believe that CBG"s hormonal role is compatible with a hypothesis that encompasses the view that unbound steroid hormones can diffuse into cells in some tissues and that both free and bound steroid can enter cells in others. Steroids 121-128 serpin family A member 6 Homo sapiens 30-33 2841062-9 1988 The association of reduced plasma cortisol and decreased CBG binding capacity in EH may be closely related to altered steroid metabolism, which may be partly explained by an abnormality resembling a relative deficiency in adrenal 17 alpha- and 11 beta-hydroxylation. Steroids 118-125 serpin family A member 6 Homo sapiens 57-60 3665128-4 1987 These changes suggest that both endogenous and exogenous glucocorticoids can modulate circulating levels of CBG and may have important implications for patients receiving steroid therapy. Steroids 171-178 serpin family A member 6 Homo sapiens 108-111 3579210-5 1987 There was, however, a linear relationship between TBC and the progesterone + cortisol sum, such that a unit increase in TBC was accompanied by an approximate unit increase in the total concentration of the two main transcortin binding steroids. Steroids 235-243 serpin family A member 6 Homo sapiens 215-226 3475428-3 1986 The association of reduced plasma cortisol and CBG binding capacity in EH may be closely related to altered steroid metabolism which may be partly explained by an abnormality mimicking a relative deficiency in adrenal 17 alpha- and 11 beta-hydroxylation. Steroids 108-115 serpin family A member 6 Homo sapiens 47-50 3940269-6 1986 Increasing amounts of each of the three unlabeled steroids produced progressive decrements in the binding of all three labeled steroids to transcortin.

Steroids 127-135 serpin family A member 6 Homo sapiens 139-150 3918139-6 1985 The steroid binding specificities of human and ape (CBG corticosterone greater than cortisol greater than progesterone greater than or equal to testosterone) were also different from those of Old World monkey CBG (corticosterone much greater than cortisol approximately equal to progesterone greater than testosterone). Steroids 4-11 serpin family A member 6 Homo sapiens 52-55 6323875-1 1984 We used a sensitive radioimmunoassay for corticosteroid-binding-globulin (CBG) to demonstrate that a human hepatoma-derived cell line secretes a protein which: (a) the radioimmunoassay cannot distinguish from CBG; (b) has the same Stokes" radius as CBG; (c) is absorbed by a steroid affinity column which is specific for CBG. Steroids 48-55 serpin family A member 6 Homo sapiens 74-77 3968514-6 1985 Investigation of the steroid binding characteristics of CBGv revealed a reduced association-rate constant (Ka = 1.05 X 10(9) l/mol) and dissociation half-time (12.5 min) when compared with normal CBG (Ka = 1.39 X 10(9) l/mol and 25 min at 0 degree C) but an apparently normal steroid binding specificity. Steroids 21-28 serpin family A member 6 Homo sapiens 56-59 3968514-6 1985 Investigation of the steroid binding characteristics of CBGv revealed a reduced association-rate constant (Ka = 1.05 X 10(9) l/mol) and dissociation half-time (12.5 min) when compared with normal CBG (Ka = 1.39 X 10(9) l/mol and 25 min at 0 degree C) but an apparently normal steroid binding specificity. Steroids 276-283 serpin family A member 6 Homo sapiens 56-59 6503216-2 1984 The mean (+/- SD) plasma concentration of transcortin was 45.0 +/- 6.7 mg/l in women not taking oral contraceptive steroids and 41.2 +/- 6.7 mg/l in healthy male volunteers. Steroids 115-123 serpin family A member 6 Homo sapiens 42-53 6419776-7 1983 In order to explain this discrepancy, we tested, in the present study, the specificity of PCMB on a blood plasma steroid binding protein: human transcortin. Steroids 113-120 serpin family A member 6 Homo sapiens 144-155 6676104-8 1983 The transcortin concentrations determined by the RIA (Y) and those by the conventional steroid-binding assay (X) revealed a good correlation (Y = 1.01 X + 6.25) in normal serum, and the immunoreactivity and steroid binding activity revealed a good correlation in heat and acid-inactivated transcortin. Steroids 87-94 serpin family A member 6 Homo sapiens 4-15 6676104-8 1983 The transcortin concentrations determined by the RIA (Y) and those by the conventional steroid-binding assay (X) revealed a good correlation (Y = 1.01 X + 6.25) in normal serum, and the immunoreactivity and steroid binding activity revealed a good correlation in heat and acid-inactivated transcortin. Steroids 207-214 serpin family A member 6 Homo sapiens 4-15 6645482-3 1983 A further purification on hydroxylapatite yielded pure transcortin with preserved steroid-binding activity. Steroids 82-89 serpin family A member 6 Homo sapiens 55-66 6355814-8 1983 Entrance of hydroxy groups into the steroid molecule increases the affinity to CBG; the contributions to the free energy of complex formation, resulting from individual substitutions or other alterations in the steroid molecule, are additive. Steroids 36-43 serpin family A member 6 Homo sapiens 79-82 6887851-3 1983 Recent results, obtained in several laboratories, on the physicochemical properties of the human corticosteroid-binding globulin (CBG, transcortin) makes this glycoprotein perhaps the best known one among the steroid-binding serum proteins.

Steroids 104-111 serpin family A member 6 Homo sapiens 135-146 6887851-6 1983 Influence of the entrance of hydrophilic or hydrophobic substituents into the steroid molecule illuminates the difference between typically hydrophobic binders such as the progesterone-binding globulin (PBG) of the pregnant guinea-pig and typically hydrophilic binders such as CBG. Steroids 78-85 serpin family A member 6 Homo sapiens 277-280 6355814-8 1983 Entrance of hydroxy groups into the steroid molecule increases the affinity to CBG; the contributions to the free energy of complex formation, resulting from individual substitutions or other alterations in the steroid molecule, are additive. Steroids 211-218 serpin family A member 6 Homo sapiens 79-82 7074030-5 1982 They have one steroid binding site per CBG molecule. Steroids 14-21 serpin family A member 6 Homo sapiens 39-42 6762710-4 1980 This is due partly to saturable binding of prednisolone to transcortin in plasma, which provides more unbound drug at higher plasma concentrations of steroid.

Steroids 24-32 serpin family A member 6 Homo sapiens 76-107 31307013-6 2019 Qualitative differences in N-glycosylation at N238 also negatively affect the steroid-binding of CBG in the absence of an N-glycan at N347 caused by a T349A substitution. Steroids 78-85 serpin family A member 6 Homo sapiens 97-100 30452386-2 2019 Human CBG has a reactive center loop (RCL) which, when cleaved by neutrophil elastase (NE), disrupts its steroid-binding activity. Steroids 105-112 serpin family A member 6 Homo sapiens 6-9 30452386-3 2019 Measurements of CBG levels are typically based on steroid-binding capacity or immunoassays. Steroids 50-57 serpin family A member 6 Homo sapiens 16-19 30452386-8 2019 We found no evidence of RCL-cleaved CBG in plasma using a heat-dependent polymerization assay, and CBG that resists immunoprecipitation with a monoclonal antibody designed to specifically recognize an intact RCL, bound steroids with a high affinity. Steroids 219-227 serpin family A member 6 Homo sapiens 99-102 30452386-10 2019 Human CBG with a NE-cleaved RCL and low affinity for steroids is absent in blood samples, and CBG ELISA discrepancies likely reflect structural differences that alter epitopes recognized by specific monoclonal antibodies. Steroids 53-61 serpin family A member 6 Homo sapiens 6-9 29678493-5 2018 The analysis shows that steroids such as testosterone with low affinity for corticosteroid-binding globulin (CBG) do not significantly influence the concentration of free cortisol. Steroids 24-32 serpin family A member 6 Homo sapiens 109-112 29192420-10 2017 It has been suggested, that mitotane also affects the peripheral metabolism of steroids, especially of transcortin (CBG). Steroids 79-87 serpin family A member 6 Homo sapiens 103-114 29273683-3 2018 Glycosylation of human CBG influences its steroid-binding activity, and there are N-glycosylation sites in the reactive center loops (RCLs) of human and rat CBGs. Steroids 42-49 serpin family A member 6 Homo sapiens 23-26 29273683-4 2018 Proteolysis of the RCL of human CBG causes a structural change that disrupts steroid binding. Steroids 77-84 serpin family A member 6 Homo sapiens 32-35 29273683-5 2018 We now show that mutations of conserved N-glycosylation sites at N238 in human CBG and N230 in rat CBG disrupt steroid binding. Steroids 111-118 serpin family A member 6 Homo sapiens 79-82 29273683-7 2018 Deglycosylation of fully glycosylated human CBG or human CBG with only one N-glycan at N238 with Endo H-reduced steroid-binding affinity, while PNGase F-mediated deglycosylation does not, indicating that steroid binding is preserved by deamidation of N238 when its N-glycan is removed. Steroids 112-119 serpin family A member 6 Homo sapiens 44-47 29273683-7 2018 Deglycosylation of fully glycosylated human CBG or human CBG with only one N-glycan at N238 with Endo H-reduced steroid-binding affinity, while PNGase F-mediated deglycosylation does not, indicating that steroid binding is preserved by deamidation of N238 when its N-glycan is removed. Steroids 112-119 serpin family A member 6 Homo sapiens 57-60 29273683-8 2018 When expressed in N-acetylglucosaminyltransferase-I-deficient Lec1 cells, human and rat CBGs, and a human CBG mutant with only one glycosylation site at N238, have higher (2-4 fold) steroid-binding affinities than when produced by sialylation-deficient Lec2 cells or glycosylation-competent CHO-S cells. Steroids 182-189 serpin family A member 6 Homo sapiens 88-91 29273683-9 2018 Thus, the presence and composition of an N-glycan in this conserved position both appear to influence the steroid binding of CBG. Steroids 106-113 serpin family A member 6 Homo sapiens 125-128 28677244-5 2017 Corticosteroid-binding globulin (CBG) is a steroid binding protein that binds and transports cortisol in the blood circulation and is a potential target for endocrine disruption. Steroids 7-14 serpin family A member 6 Homo sapiens 33-36 29192420-10 2017 It has been suggested, that mitotane also affects the peripheral metabolism of steroids, especially of transcortin (CBG).
