CC -!- FUNCTION: Plays an essential role in hormone and neurotransmitter
CC calcium-dependent exocytosis and endocytosis (PubMed:17502420,
CC PubMed:28596237, PubMed:28031464). Part of the SNARE (Soluble NSF
CC Attachment Receptor) complex composed of SNAP25, STX1A and VAMP2 which
CC mediates the fusion of synaptic vesicles with the presynaptic plasma
CC membrane. STX1A and SNAP25 are localized on the plasma membrane while
CC VAMP2 resides in synaptic vesicles. The pairing of the three SNAREs
CC from the N-terminal SNARE motifs to the C-terminal anchors leads to the
CC formation of the SNARE complex, which brings membranes into close
CC proximity and results in final fusion. Participates in the calcium-
CC dependent regulation of acrosomal exocytosis in sperm
CC (PubMed:12101244). Also plays an important role in the exocytosis of
CC hormones such as insulin or glucagon-like peptide 1 (GLP-1)
CC (PubMed:17502420, PubMed:28596237, PubMed:28031464).
CC {ECO:0000269|PubMed:12101244, ECO:0000269|PubMed:17502420,

CC -!- SUBUNIT: Part of the SNARE core complex containing SNAP25, VAMP2 and
CC STX1A; this complex constitutes the basic catalytic machinery of the
CC complex neurotransmitter release apparatus (PubMed:28031464,
CC PubMed:19196426). The SNARE complex interacts with CPLX1 (By
CC similarity). Interacts with STXBP1 (PubMed:28031464). Interacts (via C-
CC terminus) with KCNB1 (via C-terminus); the interaction increases in a
CC calcium-dependent manner and induces a pore-independent enhancement of
CC exocytosis in neuroendocrine cells, chromaffin cells, pancreatic beta
CC cells and from the soma of dorsal root ganglia (DRG) neurons (By
CC similarity). Interacts with SYTL4 (PubMed:12101244). Interacts with
CC STXBP6 (By similarity). Interacts with PLCL1 (via C2 domain)
CC (PubMed:23341457). Interacts with OTOF (PubMed:17055430). Interacts
CC with LGI3 (PubMed:18760330). Interacts with SLC6A4 (By similarity).
CC Interacts with SYT6 and SYT8; the interaction is Ca(2+)-dependent
CC (PubMed:15774481). Interacts with VAMP8 (PubMed:28031464). Interacts
CC with SNAP23 (PubMed:28031464). Interacts with VAPA and SYBU (By
CC similarity). Interacts with PRRT2 (PubMed:29056747). Interacts with
CC SEPT8 (By similarity). Interacts with STXBP5L (PubMed:21998599).
CC Interacts with synaptotagmin-1/SYT1 (By similarity).Interacts with
CC SEPTIN5; in the cerebellar cortex (PubMed:17296554). Interacts with
CC SEPTIN4; in the striatum (PubMed:17296554).
