CATEGORY

regulatory , structural protein , transport

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,organelle,mitochondria,outer
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,cytosolic,vesicle
text	fusion of synaptic vesicles to target membranes
	VAMP1 and VAMP2, both co-sediment and co-localize with NPPA

basic FUNCTION	soluble N ethylmaleimide-sensitive factor-attachment protein receptor, SNARE protein
	calcium-dependent role in the docking and fusion of synaptic vesicles with the presynaptic membrane
	playing a central role in neural exocytosis
	its cleavage modifies the coupling between channels and release-competent vesicles
	potentially having a vital role in a subset of central nervous system tissues
	its structure is clearly controlled by protein-lipid interactions
	with VAMP2, and syntaxin-4 regulate NPPA release from cardiac myocyte
	with other VAMPs, has differential membrane fusion capacities, and imply that with the exception of VAMP5, VAMPs are essentially redundant in mediating fusion with plasma membrane t-SNAREs
	dual role of VAMP1, SNAP25, STX1A in exo- and endocytosis suggests that SNARE proteins may be molecular substrates contributing to the exocytosis-endocytosis coupling, which maintains exocytosis in secretory cells

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

exocytosis transport

PATHWAY

metabolism

signaling

neurotransmission

a component	constituent of a synaptic core complex with syntaxin and synaptosome associated proteins (SNAP25)
	three SNAREs, STX4, VAMP1 and VAMP2, form a SNARE complex inside cardiac myocytes

INTERACTION

DNA

RNA

small molecule

protein	binding to t-SNARES, syntaxin (STX) and SNAP25 after the fusion of synaptic vesicles to plasma membrane
	interacting with VAPA and VAPB
	interacting with BCAP29
	dual role of SNAP25 and VAMP1 in both exocytosis and slow endocytosis at conventional synapses
