Hypothetic models of VAMP2 conformations and engagement in SNARE complex assembly for neurotransmitter release

Vesicle-associated membrane protein 2 (VAMP2) is a protein that in humans is encoded by the VAMP2 gene.[5][6]

Function

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. VAMP2 is a member of the vesicle-associated membrane protein (VAMP)/synaptobrevin family. VAMP2 is thought to participate in neurotransmitter release at a step between docking and fusion. Mice lacking functional synaptobrevin2/VAMP2 gene cannot survive after birth, and have a dramatically reduced synaptic transmission, around 10% of control.[7] The protein forms a stable complex with syntaxin, synaptosomal-associated protein, 25 kD, and complexin. It also forms a distinct complex with synaptophysin.[6]

Clinical significance

Heterozygous mutations in VAMP2 cause a neurodevelopmental disorder with hypotonia and autistic features (with or without hyperkinetic movements).[8][9][10]

Interactions

VAMP2 has been shown to interact with:
