|Product Overview :
||Recombinant human VAMP4 protein, fused to His-tag at C-terminus, was expressed inE.coliand purified by using conventional chromatography. MW = 14.5 kDa (123aa).
||VAMP4, also known as vesicle-associated membrane protein 4, is a member of the synaptobrevin family involved in docking and/or fusion of vesicles with cell membrane. This protein is enriched in the trans-Golgi network and may play a role in trans-Golgi network-to-endosome transport. VAMP4 is involved in the pathway that functions to remove an inhibitor (probably synaptotagmin-4) of calcium-triggered exocytosis during the maturation of secretory granules.
