Cyclic GMP 164-168 rhodopsin Homo sapiens 187-196 2560768-4 1989 The results of the theoretical treatment predict that (i) the presence of cGMP in rod outer segment inhibits the rhodopsin phosphorylation and (ii) rhodopsin phosphorylation process is much faster than what has been reported in the literature. Cyclic GMP 74-78 rhodopsin Homo sapiens 113-122 2560768-4 1989 The results of the theoretical treatment predict that (i) the presence of cGMP in rod outer segment inhibits the rhodopsin phosphorylation and (ii) rhodopsin phosphorylation process is much faster than what has been reported in the literature.

Lipid Bilayers 316-329 rhodopsin Homo sapiens 136-145 2780545-5 1989 Evidence for these regions of interaction of rhodopsin and Gt comes from the ability of synthetic peptides comprising these regions to compete with metarhodopsin II for binding to Gt. Peptides 98-106 rhodopsin Homo sapiens 45-54 2529919-0 1989 [Study of thermo-stabilizing effect of tocopherol on rhodopsin in the presence of fatty acids using the method of differential scanning calorimetry].

Guanosine Triphosphate 15-18 rhodopsin Homo sapiens 128-137 2497769-6 1989 Recombination of purified fluorescent derivatives of G-protein with purified rhodopsin reconstituted in lipid vesicles restored the light-activated Gpp(NH)p binding to a level comparable to that measured with unlabeled G-protein. Guanylyl Imidodiphosphate 148-156 rhodopsin Homo sapiens 77-86 2706205-9 1989 This may indicate that cellular immunity has an important role in the pathogenesis of rhodopsin-induced EAU. Water 104-107 rhodopsin Homo sapiens 86-95 2540811-9 1989 These data indicate that (1), in the transition from rhodopsin to metarhodopsin II, major protein conformational changes are occurring near the lysine-retinal linkage whereas the ring portion of the chromophore remains deeply buried within the protein and (2) pigment absorptions characteristic of the metarhodopsin I and II states may be due to specific protein-chromophore interactions near the region of the chromophore ring.

Phosphatidylcholines 210-229 rhodopsin Homo sapiens 197-206 2631391-9 1989 These findings support the hypothesis that when rhodopsin is bleached IRBP transports all-trans retinol from the retina to the pigment epithelium and that it delivers 11-cis retinal to the rod outer segments for rhodopsin regeneration.

Cysteine 48-51 rhodopsin Homo sapiens 79-88 2846571-7 1988 Binding of T alpha to rhodopsin and the ADP-ribosylation of T alpha by pertussis toxin, both of which are enhanced in the presence of T beta gamma, were inhibited by vanadate. Vanadates 166-174 rhodopsin Homo sapiens 22-31 3138543-1 1988 The recent cloning of the complementary DNAs and/or genes for several receptors linked to guanine nucleotide regulatory proteins including the adrenergic receptors (alpha 1, alpha 2A, alpha 2B, beta 1, beta 2), several subtypes of the muscarinic cholinergic receptors, and the visual "receptor" rhodopsin has revealed considerable similarity in the primary structure of these proteins.

Peptides 91-99 rhodopsin Homo sapiens 45-54 2844605-5 1988 In the presence of ATP arrestin cross-linked to both PDE and rhodopsin during the quench phenomenon. Adenosine Triphosphate 19-22 rhodopsin Homo sapiens 61-70 2844605-6 1988 Removal of ATP from the reaction mixture essentially abolished the cross-link with PDE, just as ATP omission abolishes quench, but significantly increased the cross-link to rhodopsin. Adenosine Triphosphate 11-14 rhodopsin Homo sapiens 173-182 2844605-8 1988 The data are consistent with a model of quench in which photolyzed rhodopsin (R*) catalyzes the formation of an activated form of arrestin, which dissociates from R* in the presence of ATP, and binds to PDEs, thereby deactivating them.

Guanosine Triphosphate 66-69 rhodopsin Homo sapiens 25-34 2456151-3 1988 Photo-excited rhodopsin passes through a series of transient states, and the purpose of this study is to identify the earliest state that interacts with the GTP-binding protein and thus activate the PDE.

Serine 146-152 rhodopsin Homo sapiens 36-45 9099692-2 1997 We report here that newly synthesized docosahexaenoyl (DHA) phospholipids are sequestered and cotransported by rhodopsin-bearing post-Golgi vesicles to ROS. docosahexaenoyl (dha) phospholipids 38-73 rhodopsin Homo sapiens 111-120 9099692-9 1997 At the same time, newly synthesized [35S]rhodopsin shifted from the ER and Golgi toward TGN and post-Golgi fractions. Sulfur-35 37-40 rhodopsin Homo sapiens 41-50 9099692-10 1997 Therefore, sequestration and association of [35S]rhodopsin and [3H]DHA-lipids in a TGN membrane domain occurs prior to their exit and subsequent vectorial cotransport on post-Golgi vesicles to ROS. Sulfur-35 45-48 rhodopsin Homo sapiens 49-58 9197578-2 1997 We here present the clinical phenotype in 6 patients from a family with autosomal dominant retinitis pigmentosa found to carry a point mutation in the rhodopsin gene (arginine-135-tryptophan). arginine-135-tryptophan 167-190 rhodopsin Homo sapiens 151-160 9152227-6 1997 CONCLUSIONS: Like rhodopsin, the folding of the cone opsins appears to be dependent on the formation of a disulfide bond between the third transmembrane helix and the second extracellular loop.

Tryptophan 131-134 rhodopsin Homo sapiens 68-77 8864113-2 1996 Such changes in rhodopsin were explored by construction of double cysteine mutants, each containing one cysteine at the cytoplasmic end of helix C and one cysteine at various positions in the cytoplasmic end of helix F. Magnetic dipolar interactions between spin labels attached to these residues revealed their proximity, and changes in their interaction upon rhodopsin light activation suggested a rigid body movement of helices relative to one another. Cysteine 66-74 rhodopsin Homo sapiens 16-25 8864113-3 1996 Disulfide cross-linking of the helices prevented activation of transducin, which suggests the importance of this movement for activation of rhodopsin. Disulfides 0-9 rhodopsin Homo sapiens 140-149 8901623-3 1996 The synthesis is mediated by retinaldehyde dehydrogenases which convert some of the chromophore all-trans retinaldehyde, released from bleached rhodopsin, into RA. Retinaldehyde 96-119 rhodopsin Homo sapiens 144-153 8901623-7 1996 Invertebrates differ from vertebrates in the mechanism of chromophore regeneration: while in the invertebrate visual cycle the chromophore remains bound, it is released as free all-trans retinaldehyde from illuminated vertebrate rhodopsin. trans retinaldehyde 181-200 rhodopsin Homo sapiens 229-238 8841383-3 1996 The effect of membrane cholesterol on rhodopsin was investigated using three independent techniques: thermal bleaching, differential scanning calorimetry (DSC) and activation of the cGMP cascade. Cholesterol 23-34 rhodopsin Homo sapiens 38-47 8841383-4 1996 Rhodopsin exhibited an increased resistance to thermally induced bleaching as the membrane cholesterol level was increased. Cholesterol 91-102 rhodopsin Homo sapiens 0-9 8841383-7 1996 These results suggest that cholesterol affects the disk membrane properties such that thermally induced unfolding is inhibited, thus stabilizing the rhodopsin structure.

Guanosine Diphosphate 88-91 rhodopsin Homo sapiens 26-35 8810308-5 1996 We propose that Glu134 and Arg135 constitute the site that directly provides the signal from rhodopsin to activate GDP release from Gt.

Schiff Bases 135-146 rhodopsin Homo sapiens 79-88 8038384-1 1994 The retinal chromophores of both rhodopsin and bacteriorhodopsin are bound to their apoproteins via a protonated Schiff base. Schiff Bases 113-124 rhodopsin Homo sapiens 33-42 8038384-2 1994 We have employed continuous-flow resonance Raman experiments on both pigments to determine that the exchange of a deuteron on the Schiff base with a proton is very fast, with half-times of 6.9 +/- 0.9 and 1.3 +/- 0.3 ms for rhodopsin and bacteriorhodopsin, respectively. Deuterium 114-122 rhodopsin Homo sapiens 224-233 8038384-2 1994 We have employed continuous-flow resonance Raman experiments on both pigments to determine that the exchange of a deuteron on the Schiff base with a proton is very fast, with half-times of 6.9 +/- 0.9 and 1.3 +/- 0.3 ms for rhodopsin and bacteriorhodopsin, respectively. Schiff Bases 130-141 rhodopsin Homo sapiens 224-233 8038384-6 1994 The relatively slow calculated exchange rates are essentially due to the high pKa values of the Schiff base in both rhodopsin (pKa > 17) and bacteriorhodopsin (pKa approximately 13.5).

Schiff Bases 160-171 rhodopsin Homo sapiens 175-184 8106358-3 1994 In order to characterize the molecular interaction between rhodopsin and arrestin, we have studied the ability of synthetic peptides from the proposed cytoplasmic loops of rhodopsin to inhibit arrestin binding. Peptides 124-132 rhodopsin Homo sapiens 172-181 8305429-4 1994 The extent of phosphorylation was found to be limited by two mechanisms: (1) binding of arrestin to phosphorylated rhodopsin (one to three phosphate groups) appeared to prevent further phosphorylation (arrestin has also been observed to promote the initial phosphorylation of rhodopsin at 338Ser in rod outer segment homogenates); and (2) reduction of the photolyzed chromophore all-trans-retinal to all-trans-retinol prevented phosphorylation at more than three sites. Phosphates 139-148 rhodopsin Homo sapiens 115-124 8305429-5 1994 We propose that previous observations of higher levels of rhodopsin phosphorylation may be the result of the removal of endogenous arrestin, or of exceeding the capacity of retinol dehydrogenase activity by intense bleaches (e.g., by exhausting endogenous NADPH). NADP 256-261 rhodopsin Homo sapiens 58-67 8110774-2 1994 Approximately 70% of the rhodopsin was depalmitoylated in rod outer segments by a mild hydroxylamine treatment that resulted in minimal bleaching of rhodopsin.

Cyclic GMP 17-21 rhodopsin Homo sapiens 70-79 8170923-7 1994 The approach has provided a powerful diagnostic tool for identifying GPCRs, and results are consistent with previous observations that the pheromone, cAMP and secretin-like receptors belong to separate families--these bear their own unique sequence fingerprints by which they may be distinguished from the rhodopsin-like superfamily. Cyclic AMP 150-154 rhodopsin Homo sapiens 306-315 8121492-0 1994 Calcium controls light-triggered formation of catalytically active rhodopsin. Calcium 0-7 rhodopsin Homo sapiens 67-76 8121492-3 1994 Calcium seems to exert several coordinated effects on the cyclic GMP cascade: a fall in [Ca2+] stimulates cGMP synthesis, increases the affinity of the cGMP-gated channel for cGMP and accelerates rhodopsin deactivation by phosphorylation.

Hydrogen 110-118 rhodopsin Homo sapiens 54-63 8232538-3 1993 The random spontaneous events are strongly temperature-dependent and have been attributed to thermal isomerizations of the vitamin A chromophore of rhodopsin, the light-sensitive molecule in photoreceptors. Vitamin A 123-132 rhodopsin Homo sapiens 148-157 8232538-5 1993 We propose that photoreceptor noise results from the thermal isomerization of a relatively unstable form of rhodopsin, one in which the Schiff-base linkage between the chromophore and protein is unprotonated.
