Summary: Enables several functions, including calcium-dependent protein binding activity; syntaxin-1 binding activity; and transmembrane transporter binding activity. Involved in several processes, including SNARE complex assembly; regulation of delayed rectifier potassium channel activity; and synaptic vesicle exocytosis. Located in neuron projection terminus; plasma membrane; and secretory vesicle. Part of several cellular components, including synaptobrevin 2-SNAP-25-syntaxin-1a complex; synaptobrevin 2-SNAP-25-syntaxin-1a-complexin I complex; and synaptobrevin 2-SNAP-25-syntaxin-1a-complexin II complex. Is active in postsynaptic cytosol; postsynaptic density; and synaptic vesicle membrane. Orthologous to human VAMP2 (vesicle associated membrane protein 2).

By using in-cell NMR spectroscopy study described the dynamic membrane association of rat VAMP2 SNARE motif in mammalian cells, and the structural change of VAMP2 upon the change of intracellular lipis. In contrast to the non-raft region, the membrane region of cholesterol-rich lipid raft markedly weakens the membrane association of VAMP2 SNARE motif, which releases the SNARE motif and facilitates the SNARE assembly.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
