ARF6 Antibody – Rabbit Polyclonal

This gene encodes a member of the human ARF gene family, which is part of the RAS superfamily. The ARF genes encode small guanine nucleotide-binding proteins that stimulate the ADP-ribosyltransferase activity of cholera toxin and play a role in vesicular trafficking and as activators of phospholipase D. The product of this gene is localized to the plasma membrane, and regulates vesicular trafficking, remodelling of membrane lipids, and signaling pathways that lead to actin remodeling. A pseudogene of this gene is located on chromosome 7. [provided by RefSeq, Jul 2008]

ARF6: GTP-binding protein involved in protein trafficking; regulates endocytic recycling and cytoskeleton remodeling. May modulate vesicle budding and uncoating within the Golgi apparatus. Functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase. Involved in the regulation of dendritic spine development. Contributes to the regulation of dendritic branching and filopodia extension. Interacts with ARHGAP21, ASAP2, HERC1, PIP5K1C and UACA. Interacts with NCS1/FREQ at the plasma membrane. Interacts with RAB11FIP3 and RAB11FIP4. Interacts with USP6 (via Rab-GAP TBC domain). Interacts with ECM29. Interacts with TBC1D24. Belongs to the small GTPase superfamily. Arf family.
