Ras-related protein Rab-27B

UniProtKB accession:  Q99P58

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 (By similarity). Plays a role in NTRK2/TRKB axonal anterograde transport by facilitating the association of NTRK2/TRKB with KLC1 (By similarity). May be involved in targeting uroplakins to urothelial apical membranes (By similarity).
