Calcium 0-7 annexin A7 Homo sapiens 22-29 9078249-1 1997 Synexin (annexin VII) is a member of the annexin family of calcium and phospholipid binding proteins that promote calcium-dependent aggregation and fusion of lipid vesicles or secretory granules. Calcium 59-66 annexin A7 Homo sapiens 0-7 9078249-1 1997 Synexin (annexin VII) is a member of the annexin family of calcium and phospholipid binding proteins that promote calcium-dependent aggregation and fusion of lipid vesicles or secretory granules. Calcium 59-66 annexin A7 Homo sapiens 9-20 9078249-1 1997 Synexin (annexin VII) is a member of the annexin family of calcium and phospholipid binding proteins that promote calcium-dependent aggregation and fusion of lipid vesicles or secretory granules. Calcium 114-121 annexin A7 Homo sapiens 0-7 9078249-1 1997 Synexin (annexin VII) is a member of the annexin family of calcium and phospholipid binding proteins that promote calcium-dependent aggregation and fusion of lipid vesicles or secretory granules. Calcium 114-121 annexin A7 Homo sapiens 9-20 9078249-3 1997 In this study, we characterized calcium-dependency of synexin binding to lamellar bodies and plasma membranes, since such binding is the initial, and, therefore, may be the rate-limiting step in membrane aggregation and fusion. Calcium 32-39 annexin A7 Homo sapiens 54-61 9078249-4 1997 The binding of biotinylated synexin to lamellar bodies and plasma membranes increased in a calcium-dependent manner reaching a maximum at approx. Calcium 91-98 annexin A7 Homo sapiens 28-35 9078249-9 1997 The calcium kinetics were noticeably similar for synexin binding to lamellar bodies and plasma membranes, aggregation of lamellar bodies, and fusion of lamellar bodies with lipid vesicles. Calcium 4-11 annexin A7 Homo sapiens 49-56 9078249-10 1997 At low calcium concentrations, aggregation of lamellar bodies could be increased with increasing synexin concentration, and arachidonic acid increased all three parameters (binding, aggregation, and fusion) in a similar manner. Calcium 7-14 annexin A7 Homo sapiens 97-104 9078249-11 1997 The effects of calcium and arachidonic acid on these three parameters suggest that synexin binding to lamellar bodies may be a rate-determining step for fusion during surfactant secretion. Calcium 15-22 annexin A7 Homo sapiens 83-90 9078249-12 1997 Furthermore, at near physiological calcium levels, the membrane fusion may be enhanced by elevated concentrations of synexin and polyunsaturated fatty acids. Calcium 35-42 annexin A7 Homo sapiens 117-124
