Anti-Vinculin, clone [7E10]

Anti-Vinculin antibody is purified via Protein A prification. Vinculin antibody is human, mouse, rat, rabbit and chicken reactive. At least three isoforms of Vinculin are known to exist. Protein function: May be a guanine exchange factor (GEF) for Rab21, Rab32 and Rab38 and regulate endosome dynamics (PubMed:16525121, PubMed:18477474). May regulate the participation of VAMP7 in membrane fusion events, in vitro inhibits VAMP7-mediated SNARE complex formation by trapping VAMP7 in a closed, fusogenically inactive conformation (PubMed:23104059). Involved in peripheral melanosomal distribution of TYRP1 in melanocytes, the function, which probably is implicating vesicle-trafficking, includes cooperation with Rab32, Rab38 and VAMP7. Involved in the regulation of neurite growth, the function seems to require its GEF activity, probably towards Rab21, and VAMP7 but not Rab32/38. Proposed to be involved in Golgi sorting of VAMP7 and transport of VAMP7 vesicles to the cell surface, the function seems to implicate kinesin heavy chain isoform 5 proteins, GOLGA4, RAB21 and MACF1 (PubMed:22705394). Required for the colocalization of VAMP7 and Rab21, probably on TGN sites (PubMed:19745841). Involved in GLUT1 endosome-to-plasma membrane trafficking, the function is dependent of association with VPS29 (PubMed:24856514). [The UniProt Consortium]
