WB Positive detected ：Rat brain tissue lysate

Function ： Plays an essential role in hormone and neurotransmitter calcium-dependent exocytosis and endocytosis (PubMed:26635000). Part of the SNARE (Soluble NSF Attachment Receptor) complex composed of SNAP25, STX1A and VAMP2 which mediates the fusion of synaptic vesicles with the presynaptic plasma membrane. STX1A and SNAP25 are localized on the plasma membrane while VAMP2 resides in synaptic vesicles. The pairing of the three SNAREs from the N-terminal SNARE motifs to the C-terminal anchors leads to the formation of the SNARE complex, which brings membranes into close proximity and results in final fusion. Participates in the calcium-dependent regulation of acrosomal exocytosis in sperm (PubMed:23091057). Plays also an important role in the exocytosis of hormones such as insulin or glucagon-like peptide 1 (GLP-1) (By similarity)..

Tissue specificity ：[Isoform 1]: Highly expressed in embryonic spinal cord and ganglia and in adult cerebellum and cerebral cortex..,[Isoform 2]: Expressed in heart, liver, fat, skeletal muscle, kidney and brain..

Subcellular locationi ：Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane,Single-pass type IV membrane protein. Cell junction, synapse, synaptosome. Cell membrane.

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 1% w/v BSA, 1X TBST at 4°C overnight.
