we purified synexin-like proteins from bovine lung cytosolic fraction, and evaluated their effect on the fusion of isolated lamellar bodies and plasma membrane fractions. chromaffin 69-79 annexin A7 Bos taurus 6-13 6112701-3 1980 We have discovered and isolated a new 47,000 MW protein (synexin) from adrenal medulla tissue that fuses chromaffin granule membranes only in the presence of calcium. chromaffin 105-115 annexin A7 Bos taurus 57-64 6112701-4 1980 Synexin activity was detected in a number of secretory tissues including human platelets and bovine brain, and the synexin molecule was found by immunofluorescent cytochemistry to be localized to the cytoplasm of chromaffin cells. chromaffin 213-223 annexin A7 Bos taurus 115-122 1423500-0 1992 Immunolocalization of synexin (annexin VII) in adrenal chromaffin granules and chromaffin cells: evidence for a dynamic role in the secretory process. chromaffin 55-65 annexin A7 Bos taurus 22-29 1423500-0 1992 Immunolocalization of synexin (annexin VII) in adrenal chromaffin granules and chromaffin cells: evidence for a dynamic role in the secretory process. chromaffin 55-65 annexin A7 Bos taurus 31-42 1423500-2 1992 Using a monoclonal antibody against synexin, Mab 10E7, and immunogold, we carried out a semiquantitative localization study of synexin in bovine adrenal medullary chromaffin granules, and in resting and nicotine-stimulated adrenal chromaffin cells. chromaffin 163-173 annexin A7 Bos taurus 127-134 1423500-3 1992 Isolated chromaffin granules contained very little synexin, whereas chromaffin granules aggregated with synexin (24 micrograms/mg) and Ca2+ (1 mM) clearly showed synexin-associated immunogold particles in the vicinity of the granule membrane (1.88 gold particles per granule profile). chromaffin 68-78 annexin A7 Bos taurus 104-111 1423500-3 1992 Isolated chromaffin granules contained very little synexin, whereas chromaffin granules aggregated with synexin (24 micrograms/mg) and Ca2+ (1 mM) clearly showed synexin-associated immunogold particles in the vicinity of the granule membrane (1.88 gold particles per granule profile). chromaffin 68-78 annexin A7 Bos taurus 104-111 1423500-7 1992 We conclude that synexin is involved in the secretory process in chromaffin cells. chromaffin 65-75 annexin A7 Bos taurus 17-24 2974861-3 1988 Synexin is a 47,000 Mr calcium-binding protein, initially discovered in the bovine adrenal medulla, which binds to granule membranes and to inner aspects of chromaffin cell plasma membranes. chromaffin 157-167 annexin A7 Bos taurus 0-7 2974861-4 1988 Synexin causes chromaffin granules to aggregate, and such aggregates can be caused to fuse in the additional presence of arachidonic acid. chromaffin 15-25 annexin A7 Bos taurus 0-7 2974861-5 1988 Synexin also mediates the direct fusion of liposomes and chromaffin granule ghosts. chromaffin 57-67 annexin A7 Bos taurus 0-7 2960380-0 1987 Synexin-mediated fusion of bovine chromaffin granule ghosts. chromaffin 34-44 annexin A7 Bos taurus 0-7 2960380-2 1987 Synexin induces chromaffin granule ghosts to fuse one to another, a process which is followed continuously and quantitatively by monitoring the mixing of the intragranular aqueous compartments. chromaffin 16-26 annexin A7 Bos taurus 0-7 2960380-14 1987 We conclude that the coincident pCa and pH sensitivity of synexin-mediated binding to chromaffin granule membranes and their subsequent fusion might be associated with physiological changes in the concentration of both cations in the cytoplasm of secreting chromaffin cells. chromaffin 86-96 annexin A7 Bos taurus 58-65 2960380-14 1987 We conclude that the coincident pCa and pH sensitivity of synexin-mediated binding to chromaffin granule membranes and their subsequent fusion might be associated with physiological changes in the concentration of both cations in the cytoplasm of secreting chromaffin cells. chromaffin 257-267 annexin A7 Bos taurus 58-65 6121822-0 1982 Further characterization of the aggregation and fusion of chromaffin granules by synexin as a model for compound exocytosis. chromaffin 58-68 annexin A7 Bos taurus 81-88 6121822-1 1982 Synexin was isolated from bovine liver and found to aggregate adrenal chromaffin granules in the same Ca2+-dependent manner as previously described for adrenal synexin. chromaffin 70-80 annexin A7 Bos taurus 0-7 6121822-2 1982 The chromaffin granule aggregating activity of liver synexin was blocked in vitro by the addition of an antibody prepared to the 47,000 molecular weight band extracted from an SDS gel of an adrenal medullary synexin preparation. chromaffin 4-14 annexin A7 Bos taurus 53-60 6121822-2 1982 The chromaffin granule aggregating activity of liver synexin was blocked in vitro by the addition of an antibody prepared to the 47,000 molecular weight band extracted from an SDS gel of an adrenal medullary synexin preparation. chromaffin 4-14 annexin A7 Bos taurus 208-215 6121822-3 1982 Chromaffin granules aggregated by synexin fused when exposed to cis-unsaturated fatty acids at concentrations comparable to those released from phospholipids by stimulated secretory cells. chromaffin 0-10 annexin A7 Bos taurus 34-41 6121822-5 1982 The aggregation and fusion of chromaffin granules thus appears to be a useful model system for studying synexin from diverse tissues and for testing pharmacologically or toxicologically active substances for effects on secretory systems. chromaffin 30-40 annexin A7 Bos taurus 104-111
