VAMP2

The protein encoded by this gene is a member of the vesicle-associated membrane protein (VAMP)/synaptobrevin family. Synaptobrevins/VAMPs, syntaxins, and the 25-kD synaptosomal-associated protein SNAP25 are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane. This gene is thought to participate in neurotransmitter release at a step between docking and fusion. The protein forms a stable complex with syntaxin, synaptosomal-associated protein, 25 kD, and synaptotagmin. It also forms a distinct complex with synaptophysin. It is a likely candidate gene for familial infantile myasthenia (FIMG) because of its map location and because it encodes a synaptic vesicle protein of the type that has been implicated in the pathogenesis of FIMG.

Interaction

Part of the SNARE core complex containing SNAP25, VAMP2 and STX1A. This complex binds to CPLX1. Interacts with BVES and STX4 (By similarity). Interacts with VAPA and VAPB. Interacts with WDFY2, PRKCZ and PRKCI (PubMed:17313651). Forms a complex with WDFY2 and PRKCZ (PubMed:17313651). Interacts (via N-terminus) with KCNB1 (via N-terminus and C-terminus); stimulates the channel inactivation rate of KCNB1 (By similarity). Interacts with SEPT8; the interaction inhibits interaction of VAMP2 with SYP. Interacts with SYP; the interaction is inhibited by interaction with SEPT8 (By similarity). Interacts with PICALM (PubMed:22118466, PubMed:21808019). Interacts with alpha-synuclein/SNCA (PubMed:20798282). Interacts with STX3 (By similarity).
