ARF1 is a GTP-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. The GTP-bound form interacts with PICK1 to limit PICK1-mediated inhibition of Arp2/3 complex activity; the function is linked to AMPA receptor (AMPAR) trafficking, regulation of synaptic plasicity of excitatory synapses and spine shrinkage during long-term depression (LTD).

For an antibody with an established history of published use targeting the same protein, see our ARF1 Antibody 1A9/5 / ADP-Ribosylation Factor 1 Antibody.
Titration of the ARF1 Rabbit Polyclonal Antibody may be required due to differences in protocols and secondary/substrate sensitivity.
A portion of amino acids 80-106 from the human protein was used as the immunogen for this ARF1 Rabbit Polyclonal Antibody.
Aliquot the ARF1 Rabbit Polyclonal Antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
