DESCRIPTION

Also known as RB27B_HUMAN, RAB27B. Small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins to regulate homeostasis of late endocytic pathway, including endosomal positioning, maturation and secretion (PubMed:30771381). Plays a role in NTRK2/TRKB axonal anterograde transport by facilitating the association of NTRK2/TRKB with KLC1 (PubMed:21775604). May be involved in targeting uroplakins to urothelial apical membranes (By similarity). Interacts with SYTL2, SYTL4, MYRIP and MLPH. Interacts with RPH3A and RPH3A (By similarity). Interacts (GDP-bound form preferentially) with DENND10 (PubMed:30771381).
