Anti-Rab27B Antibody

RAB27B, also known as C25KG, is a member of the Rab GTPase superfamily. RAB27B acts as a lipid anchoring protein that is prenylated and works in vesicular fusion and protein trafficking within cells. The protein is most highly expressed in testis but can be expressed in other cell types as well. Because Rab27B is widely expressed in various tissues together with Rab27A and RAB27B has been found to have the ability to bind all of the Rab27A effectors that have been tested, Rab27A and Rab27B were initially thought to function redundantly by sharing common Rab27 effectors. However, recent evidence has indicated that by interacting with different Rab27 effectors Rab27A and Rab27B play different roles in special types of secretion (e.g. exosome secretion and mast cell secretion) even within the same cell type. Rab27B is particularly important for regulating protein secretion by pancreatic acinar cells, for instance.
