Guanosine Diphosphate 84-87 insulin Homo sapiens 26-33 21187662-7 2011 Since glucose converts Rab27a from the GTP- to GDP-bound form, we suggested that Rab27a plays a crucial role in stimulus-endocytosis coupling in pancreatic beta-cells, and that this is the key molecule for membrane recycling of insulin granules. Guanosine Diphosphate 47-50 insulin Homo sapiens 228-235 21187662-8 2011 In this review, we provide an overview of the roles of Rab27a and its GTP- and GDP-dependent effectors in the insulin secretory pathway of pancreatic beta-cells. Guanosine Diphosphate 79-82 insulin Homo sapiens 110-117 16306371-0 2005 Rho guanosine diphosphate-dissociation inhibitor plays a negative modulatory role in glucose-stimulated insulin secretion. Guanosine Diphosphate 4-25 insulin Homo sapiens 104-111 16306371-2 2005 However, very little is known with regard to potential regulation by G-protein regulatory factors (e.g., the guanosine diphosphate-dissociation inhibitor [GDI]) of insulin secretion from the islet beta-cell. Guanosine Diphosphate 109-130 insulin Homo sapiens 164-171 7918472-3 1994 Herein, we characterize nucleoside diphosphokinase (NDP kinase) activity, which catalyzes the transphosphorylation of nucleotide diphosphate (e.g., GDP) to nucleotide triphosphates (e.g., GTP) in insulin-secreting cells. Guanosine Diphosphate 148-151 insulin Homo sapiens 196-203 7988425-5 1994 Insulin increased GEF activity in both fractions (48 +/- 12% [3H]GDP released vs. 24 +/- 6% in control plasma membranes, and 65 +/- 13% vs. 13 +/- 4% in control cytosolic fractions), whereas EGF enhanced only the plasma membrane-associated activity (43 +/- 12% of [3H]GDP release in the plasma membrane fraction and 10 +/- 2% in the cytosol). Guanosine Diphosphate 65-68 insulin Homo sapiens 0-7 7988425-5 1994 Insulin increased GEF activity in both fractions (48 +/- 12% [3H]GDP released vs. 24 +/- 6% in control plasma membranes, and 65 +/- 13% vs. 13 +/- 4% in control cytosolic fractions), whereas EGF enhanced only the plasma membrane-associated activity (43 +/- 12% of [3H]GDP release in the plasma membrane fraction and 10 +/- 2% in the cytosol). Guanosine Diphosphate 268-271 insulin Homo sapiens 0-7 9914469-9 1999 The monomeric GTPase Rab3A controls insulin secretion through cycling between a guanosine triphosphate liganded vesicle-bound form and a guanosine diphosphate liganded, cytosolic form. Guanosine Diphosphate 137-158 insulin Homo sapiens 36-43 8663461-1 1996 Insulin and epidermal growth factor (EGF) stimulate a rapid but transient increase in the amount of GTP bound to Ras that returns to the basal GDP-bound state within 10-30 min. Guanosine Diphosphate 143-146 insulin Homo sapiens 0-7 8139548-2 1994 Insulin-induced membrane ruffling was inhibited by microinjection of rho GDI, an inhibitory GDP/GTP exchange regulator for both rho p21 and rac p21 small GTP-binding proteins, but not inhibited by microinjection of botulinum exoenzyme C3, known to selectively ADP-ribosylate rho p21 and to impair its function. Guanosine Diphosphate 92-95 insulin Homo sapiens 0-7 8263034-0 1993 Insulin stimulates GDP release from G proteins in the rat and human liver plasma membranes. Guanosine Diphosphate 19-22 insulin Homo sapiens 0-7 8263034-7 1993 In the rat membranes, 1-100 nM glucagon (used as a positive control) stimulated [32P]GDP release by about 17% (P < .05); similarly, 0.1-100 nM insulin stimulated [32P]GDP release by 10-13% (P < .05). Guanosine Diphosphate 170-173 insulin Homo sapiens 146-153 8263034-8 1993 In the human membranes, 10 pM to 100 nM insulin stimulated [32P]GDP release by 7-10%. Guanosine Diphosphate 64-67 insulin Homo sapiens 40-47 8263034-9 1993 In the rat membranes, 10 nM insulin stimulated [32P]GDP release by 17 and 24% at 2 and 4 min, respectively (P < .05); in the human membranes, 10 nM insulin stimulated [32P]GDP release by about 9% at 2 and 4 min. Guanosine Diphosphate 52-55 insulin Homo sapiens 28-35 8263034-9 1993 In the rat membranes, 10 nM insulin stimulated [32P]GDP release by 17 and 24% at 2 and 4 min, respectively (P < .05); in the human membranes, 10 nM insulin stimulated [32P]GDP release by about 9% at 2 and 4 min. Guanosine Diphosphate 52-55 insulin Homo sapiens 151-158 8263034-9 1993 In the rat membranes, 10 nM insulin stimulated [32P]GDP release by 17 and 24% at 2 and 4 min, respectively (P < .05); in the human membranes, 10 nM insulin stimulated [32P]GDP release by about 9% at 2 and 4 min. Guanosine Diphosphate 175-178 insulin Homo sapiens 28-35 8263034-9 1993 In the rat membranes, 10 nM insulin stimulated [32P]GDP release by 17 and 24% at 2 and 4 min, respectively (P < .05); in the human membranes, 10 nM insulin stimulated [32P]GDP release by about 9% at 2 and 4 min. Guanosine Diphosphate 175-178 insulin Homo sapiens 151-158 31507338-14 2019 The insulin pump therapy can be considered cost-effective in the context of the IMSS when considering a threshold of three GDPs per capita with 43.9% probability. Guanosine Diphosphate 123-127 insulin Homo sapiens 4-11 9609111-3 1998 In the last decade, great progress has been made in understanding the molecular mechanisms which regulate the insulin mediated conversion of Ras from its inactive, GDP-bound state, to the activated GTP-bound form. Guanosine Diphosphate 164-167 insulin Homo sapiens 110-117 34551282-5 2021 Insulin-induced KARATE assembly is controlled via phosphorylation of GTP-bound KRAS4B at S181 and GDP-bound RHOA at S188 by protein kinase A. Guanosine Diphosphate 98-101 insulin Homo sapiens 0-7 3109943-1 1987 Autophosphorylation of the purified human insulin receptor tyrosyl kinase was found to be inhibited by the ras oncogene product p21 in a concentration- and GDP-dependent manner. Guanosine Diphosphate 156-159 insulin Homo sapiens 42-49 8388384-1 1993 Insulin activates the ras proto-oncogene product p21ras (Ras) by stimulating conversion of the inactive GDP-bound form of Ras to the active GTP-bound form. Guanosine Diphosphate 104-107 insulin Homo sapiens 0-7 2956255-1 1987 We have previously reported that the GDP-bound alpha-subunit of the GTP-binding protein transducin, present in outer segments of retinal rod cells (ROS), serves as a high affinity in vitro substrate (Km = 1 microM) for the insulin receptor kinase. Guanosine Diphosphate 37-40 insulin Homo sapiens 223-230 25947911-9 2015 We also demonstrated that the insulin secretagogue glucose converts Rab27a from its GTP- to GDP-bound forms. Guanosine Diphosphate 92-95 insulin Homo sapiens 30-37 31474712-0 2019 GDP-Bound Rab27a Dissociates from the Endocytic Machinery in a Phosphorylation-Dependent Manner after Insulin Secretion. Guanosine Diphosphate 0-3 insulin Homo sapiens 102-109 31474712-3 2019 We have previously shown that in response to high concentrations of glucose, guanosine 5"-diphosphate (GDP)-bound Rab27a is recruited to the plasma membrane where IQ motif-containing guanosine 5"-triphosphatase (GTPase)-activating protein 1 (IQGAP1) is expressed, and that complex formation promotes endocytosis of secretory membranes after insulin secretion. Guanosine Diphosphate 77-101 insulin Homo sapiens 341-348 31474712-3 2019 We have previously shown that in response to high concentrations of glucose, guanosine 5"-diphosphate (GDP)-bound Rab27a is recruited to the plasma membrane where IQ motif-containing guanosine 5"-triphosphatase (GTPase)-activating protein 1 (IQGAP1) is expressed, and that complex formation promotes endocytosis of secretory membranes after insulin secretion. Guanosine Diphosphate 103-106 insulin Homo sapiens 341-348 31474712-9 2019 These results suggest that IQGAP1 phosphorylated by PKCepsilon promotes the dissociation of the IQGAP1-GDP-bound Rab27a complex in pancreatic beta-cells, thereby regulating endocytosis of secretory membranes following insulin secretion.
