Human VAMP-5 Antibody

VAMP-5 (vesicle associated membrane protein 5; also myobrevin) is a member of the synaptobrevin family of proteins. Although its predicted MW is 11 kDa, it runs anomalously at 16 kDa in SDS-Page. VAMP-5 is a type IV transmembrane (TM) protein (i.e.-a type II TM protein whose C-terminus is almost completely transmembrane) that is found in both trans-Golgi and plasma membranes of myotubes (mature skeletal and cardiac muscle cells). While VAMPs are commonly associated with vesicle fusion to t-SNARE in cell membranes, VAMP-5 appears to show no such activity. Human VAMP-5 is 116 amino acids (aa) in length. It contains an N-terminal cytoplasmic region (aa 1-72) with one vSNARE coiled-coil homology domain, a 21 aa TM segment, and 23 aa C-terminal luminal domain. Over aa 1-72, human VAMP-5 shares 75% aa identity with mouse VAMP-5.
