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 VAMP2gene.[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]
