RAB9A Antibody

Ras-related protein Rab9A, also called Rab9, is a protein that in humans is encoded by the RAB9A gene. Rab9 has been localized to components of the endocytic/exocytic pathway and has been implicated in recycling of membrane receptors. It has been found that downregulation of RAB9A gene expression in HeLa cells induced severe cell vacuolation. RAB9A GTPase is directly bound by TIP47 in its active, GTP-bound conformation. Moreover, the protein increases the affinity of TIP47 for its cargo. Additionally, this gene may involved in the transport of proteins between the endosomes and the trans Golgi network. RAB9A has been shown to interact with RABEPK and TIP47.
