Product nameArf1 Activation Assay Kit
Sample typeTissue, Adherent cells, Suspension cells
Species reactivityReacts with: Mouse, Rat, Human
Arf1 Activation Assay Kit (ab211170) uses GGA3 PBD Agarose beads to selectively isolate and pull-down the active form of Arf from purified samples or endogenous lysates. Subsequently, the precipitated GTP-Arf is detected by western blot analysis using an anti-Arf1 antibody, which detects the human, mouse and rat protein.
Features: 1) non radioactive assay format; 2) fast results: 1 hour assay plus electrophoresis/blotting time; 3) includes Cdc42 positive control; 4) pink colored agarose beads for easy identification during washing and aspiration steps.
Small GTP-binding proteins (or GTPases) are a family of proteins that serve as molecular regulators in signaling transduction pathways.
Arf1 (ADP-ribosylation factor 1) is a 21 kDa protein, member of ARF gene family, which constitutes part of the Ras superfamily. The Arf proteis are categorized as class I (Arf1, Arf2, Arf3), class II (Arf4 and Arf5) and class III (Arf6), and they all share a common gene organization. Arf1 regulates a variety of biological response pathways that include vesicle and protein trafficking, organelle structure, and endocytosis. Like other small GTPases, Arf1 cycles between an inactive GDP-bound form and an active GTP-bound form: in its active (GTP-bound) state, Arf1 binds specifically to the protein-binding domain (PBD) of GGA3 to control downstream signaling cascades.

FunctionGTP-binding protein that functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase. Involved in protein trafficking among different compartments. Modulates vesicle budding and uncoating within the Golgi complex. Deactivation induces the redistribution of the entire Golgi complex to the endoplasmic reticulum, suggesting a crucial role in protein trafficking. In its GTP-bound form, its triggers the association with coat proteins with the Golgi membrane. The hydrolysis of ARF1-bound GTP, which is mediated by ARFGAPs proteins, is required for dissociation of coat proteins from Golgi membranes and vesicles.
Sequence similaritiesBelongs to the small GTPase superfamily. Arf family.
