ARF1/ARF3/ARF5/ARF6 Monoclonal Antibody (1D9), Invitrogen™

Description

MA3-060 detects ADP-ribosylation factor1 (Arf1), Arf3, Arf5 and Arf6 and about ten-fold less well with Arf4 from human, mouse and rat tissues. MA3-060 has been successfully used in Western blot, immunofluorescence, immunocytochemistry, and immunoprecipitation procedures. By Western blot, this antibody detects a single ∽21 kDa protein representing Arf in rat pancreas extract. Immunofluorescence staining of Arf in rat pancreas with MA3-060 results in staining of the cytoplasmic face of the trans-Golgi membranes. MA3-060 cannot be used to neutralize Arf in solution. The MA3-060 antigen is recombinant human Arf1.

ADP-ribosylation factor 1 (ARF1) is a member of the human ARF gene family. The family members encode small guanine nucleotide-binding proteins that stimulate the ADP-ribosyltransferase activity of cholera toxin and play a role in vesicular trafficking as activators of phospholipase D. The gene products, including 6 ARF proteins and 11 ARF-like proteins, constitute a family of the RAS superfamily. The ARF proteins are categorized as class I (ARF1, ARF2 and ARF3), class II (ARF4 and ARF5) and class III (ARF6), and members of each class share a common gene organization. The ARF1 protein is localized to the Golgi apparatus and has a central role in intra-Golgi transport. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]
