Anti-Rab4 (Ras-related Protein Rab4, Ras-related Protein Rab-4)

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. 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. Applications: Suitable for use in Western Blot.
