Human SNAP23 Antibody

SNAP23 (Synaptosomal associated protein 23; also Syndet) is a membrane-associated 23‑29 kDa member of the SNAP25 family of proteins. It is expressed in multiple cell types, including neutrophils, platelets, mast cells and adipocytes. SNAP23 is involved in vesicle exocytosis. It has been proposed that SNAP23 can associate with both vesicle and target (cell) membranes via a lipid modification. As a v-SNARE, it may interact with syntaxin-6 at the cell membrane. As a t-SNARE, in conjunction with syntaxin-4, it likely interacts with VAMP-2 and -8 on the vesicle membrane. In either case, this approximates two membranes, which subsequently fuse to create a pore. Human SNAP23 is 211 amino acids (aa) in length. It contains two t-SNARE coiled-coil homology domains (aa 14‑76 and 148‑207). Palmitoylation occurs between aa 80‑87, while phosphorylation occurs on multiple Ser/Thr residues. There is one splice variant that shows a deletion of aa 90‑142. Over aa 146‑211, human and mouse SNAP23 share 85% aa identity.
