Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

t-SNARE involved in the molecular regulation of neurotransmitter release (PubMed:8243676, PubMed:8103915). May play an important role in the synaptic function of specific neuronal systems. Associates with proteins involved in vesicle docking and membrane fusion. Regulates plasma membrane recycling through its interaction with CENPF (PubMed:16672379). Modulates the gating characteristics of the delayed rectifier voltage-dependent potassium channel KCNB1 in pancreatic beta cells (By similarity).By similarity2 Publications1 Publication

Interactioni

Subunit structurei

Part of the SNARE core complex containing SNAP25, VAMP2 and STX1A, this complex binds CPLX1 (By similarity). Found in a complex containing SYT1, SV2B and syntaxin-1 (PubMed:15466855). Found in a ternary complex with STX1A and VAMP8 (By similarity). Isoform 1 and isoform 2 interact with BLOC1S6 (PubMed:19546860). Interacts with CENPF (PubMed:16672379). Interacts with EQTN (PubMed:19285662). Interacts with HGS (By similarity). Interacts with KCNB1 (via N-terminus); reduces the voltage-dependent potassium channel KCNB1 activity in pancreatic beta cells (By similarity). Interacts with OTOF (PubMed:17055430). Interacts with RIMS1 (By similarity). Interacts with SNAPIN (PubMed:10195194). Interacts with STXBP6 (By similarity). Interacts with TRIM9 (By similarity). Interacts with ZDHHC13 (via ANK repeats) (PubMed:25253725). Interacts with ZDHHC17 (via ANK repeats) (PubMed:25253725). Associates with the BLOC-1 complex (PubMed:19546860). Interacts with HSC70 and with SYT9, forming a complex with DNAJC5 (PubMed:20847230). The interaction with SYT9 is inhibited in presence of calcium (PubMed:20847230). Interacts with PLCL1 (via C2 domain) (PubMed:23341457). Interacts with PRRT2; this interaction may impair the formation of the SNARE complex (PubMed:22832103, PubMed:27052163, PubMed:29056747).By similarity12 Publications
