Guanosine Triphosphate 79-82 annexin A7 Homo sapiens 46-57 11994295-0 2002 Protein kinase C and guanosine triphosphate combine to potentiate calcium-dependent membrane fusion driven by annexin 7. Guanosine Triphosphate 21-43 annexin A7 Homo sapiens 110-119 11994295-2 2002 Guanosine triphosphate (GTP) and its non-hydrolyzable analogues optimally enhance the phosphorylation of annexin 7 by protein kinase C in vitro. Guanosine Triphosphate 0-22 annexin A7 Homo sapiens 105-114 11994295-2 2002 Guanosine triphosphate (GTP) and its non-hydrolyzable analogues optimally enhance the phosphorylation of annexin 7 by protein kinase C in vitro. Guanosine Triphosphate 24-27 annexin A7 Homo sapiens 105-114 11994295-3 2002 Reciprocally, phosphorylation by protein kinase C significantly potentiates the binding and hydrolysis of GTP by annexin 7. Guanosine Triphosphate 106-109 annexin A7 Homo sapiens 113-122 11338180-2 2001 We studied the expression and localization of annexin VII (synexin), a Ca(2+)-/GTP-dependent membrane fusion protein, in the human CNS. Guanosine Triphosphate 79-82 annexin A7 Homo sapiens 59-66 10570150-1 1999 The mammalian anx7 gene codes for a Ca(2+)-activated GTPase, which supports Ca(2+)/GTP-dependent secretion events and Ca(2+) channel activities in vitro and in vivo. Guanosine Triphosphate 53-56 annexin A7 Homo sapiens 14-18 11278415-1 2001 Annexin 7, a Ca(2+)/GTP-activated membrane fusion protein, is preferentially phosphorylated in intact chromaffin cells, and the levels of annexin 7 phosphorylation increase quantitatively in proportion to the extent of catecholamine secretion. Guanosine Triphosphate 20-23 annexin A7 Homo sapiens 0-9 10875895-1 2000 ANX7 is a Ca(2+)/GTP-dependent membrane fusion protein, which is involved in regulating exocytotic secretion. Guanosine Triphosphate 17-20 annexin A7 Homo sapiens 0-4 9918499-6 1998 In addition, annexin VII showed hydrolytic activity towards GTP, and similarities in the mechanism of action to that of small GTP-binding proteins were found. Guanosine Triphosphate 60-63 annexin A7 Homo sapiens 13-24 9918499-6 1998 In addition, annexin VII showed hydrolytic activity towards GTP, and similarities in the mechanism of action to that of small GTP-binding proteins were found. Guanosine Triphosphate 126-129 annexin A7 Homo sapiens 13-24 9327852-0 1998 Synexin (annexin VII) hypothesis for Ca2+/GTP-regulated exocytosis. Guanosine Triphosphate 42-45 annexin A7 Homo sapiens 0-7 9327852-0 1998 Synexin (annexin VII) hypothesis for Ca2+/GTP-regulated exocytosis. Guanosine Triphosphate 42-45 annexin A7 Homo sapiens 9-20 8855260-0 1996 Membrane fusion protein synexin (annexin VII) as a Ca2+/GTP sensor in exocytotic secretion. Guanosine Triphosphate 56-59 annexin A7 Homo sapiens 24-31 8855260-0 1996 Membrane fusion protein synexin (annexin VII) as a Ca2+/GTP sensor in exocytotic secretion. Guanosine Triphosphate 56-59 annexin A7 Homo sapiens 33-44 8855260-2 1996 However, the calcium-dependent membrane fusion reaction driven by synexin (annexin VII) is an in vitro model for this process, which we have now found to be further activated by GTP. Guanosine Triphosphate 178-181 annexin A7 Homo sapiens 66-73 8855260-2 1996 However, the calcium-dependent membrane fusion reaction driven by synexin (annexin VII) is an in vitro model for this process, which we have now found to be further activated by GTP. Guanosine Triphosphate 178-181 annexin A7 Homo sapiens 75-86 8855260-3 1996 The mechanism of fusion activation depends on the unique ability of synexin to bind and hydrolyze GTP in a calcium-dependent manner, both in vitro and in vivo in streptolysin O-permeabilized chromaffin cells. Guanosine Triphosphate 98-101 annexin A7 Homo sapiens 68-75 8855260-4 1996 The required [Ca2+] for GTP binding by synexin is in the range of 50-200 microM, which is known to occur at exocytotic sites in chromaffin cells, neurons, and other cell types. Guanosine Triphosphate 24-27 annexin A7 Homo sapiens 39-46 8855260-5 1996 Previous immunolocalization studies place synexin at exocytotic sites in chromaffin cells, and we conclude that synexin is an atypical G protein that may be responsible for both detecting and mediating the Ca2+/GTP signal for exocytotic membrane fusion.
