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 ECO:0000269|PubMed:28031464, ECO:0000269|PubMed:28596237}. 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, PubMed:28821673). The SNARE complex interacts with CC CPLX1 (By similarity). Interacts with STXBP1 (PubMed:28031464, CC PubMed:21445306, PubMed:28821673). The interaction with STXBP1 promotes CC assembly of the SNARE complex (PubMed:28821673). 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 (via the H3 domain) with SLC6A4 CC (via the N-terminus); this interaction regulates SLC4A6 channel CC conductance in thalamocortical neurons (By similarity). Interacts with CC SYT6 and SYT8; the interaction is Ca(2+)-dependent (PubMed:15774481). CC Interacts with VAMP8 (PubMed:28031464). Interacts with SNAP23 CC (PubMed:28031464). Interacts with VAPA and SYBU (By similarity). CC Interacts with PRRT2 (PubMed:29056747). Interacts with SEPT8 (By CC similarity). Interacts with STXBP5L (PubMed:21998599). Interacts with CC synaptotagmin-1/SYT1 (By similarity).Interacts with SEPTIN5; in the CC cerebellar cortex (PubMed:17296554).
