Protocol Available protocols: Western Blotting Specificity / Sensitivity Rab4 Antibody detects endogenous levels of total Rab4 protein. Species Reactivity: Human, Mouse, Rat, Hamster, Monkey Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp128 of human Rab4 protein. Antibodies are purified by protein A and peptide affinity chromatography. Background Rab4 is a member of the Ras superfamily of small Rab GTPases implicated in endocytosis. Rab4 is localized at early endosomes/recycling endosomes and functions as a key regulator for sorting/recycling of membrane and proteins (1,2). Rab4 has two isoforms, Rab4A and Rab4B, both of which are localized in similar cellular compartments and are believed to have similar functions (4). Rab4 interacts with several Rab4 effectors in a complex on a special endosome site that promotes membrane/protein recycling (1,3).
