DESCRIPTION

Also known as RAB10_HUMAN, RAB10. The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes (PubMed:21248164). Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion (PubMed:21248164). That Rab is mainly involved in the biosynthetic transport of proteins from the Golgi to the plasma membrane (PubMed:21248164). Regulates, for instance, SLC2A4/GLUT4 glucose transporter-enriched vesicles delivery to the plasma membrane (By similarity). In parallel, it regulates the transport of TLR4, a toll-like receptor to the plasma membrane and therefore may be important for innate immune response (By similarity). Plays also a specific role in asymmetric protein transport to the plasma membrane (PubMed:16641372). In neurons, it is involved in axonogenesis through regulation of vesicular membrane trafficking toward the axonal plasma membrane (By similarity). In epithelial cells, it regulates transport from the Golgi to the basolateral membrane (PubMed:16641372). May play a role in the basolateral recycling pathway and in phagosome maturation (By similarity). May play a role in endoplasmic reticulum dynamics and morphology controlling tubulation along microtubules and tubules fusion (PubMed:23263280). Together with LRRK2, RAB8A, and RILPL1, it regulates ciliogenesis (PubMed:30398148). When phosphorylated by LRRK2 on Thr-73, binds RILPL1 and inhibits ciliogenesis (PubMed:30398148)., (Microbial infection) Upon Legionella pneumophila infection promotes endoplasmic reticulum recruitment and bacterial replication. Plays a role in remodeling the Legionella-containing vacuole (LCV) into an endoplasmic reticulum-like vacuole. Interacts with MYO5A; mediates the transport to the plasma membrane of SLC2A4/GLUT4 storage vesicles (PubMed:22908308). Interacts with GDI1 and with GDI2; negatively regulates RAB10 association with membranes and activation (PubMed:19570034, PubMed:26824392, PubMed:29125462). Interacts (GDP-bound form) with LLGL1; the interaction is direct and promotes RAB10 association with membranes and activation through competition with the Rab inhibitor GDI1 (By similarity). Interacts with EXOC4; probably associates with the exocyst (By similarity). Interacts (GTP-bound form) with MICALCL, MICAL1, MICAL3, EHBP1 and EHBP1L1; at least in case of MICAL1 two molecules of RAB10 can bind to one molecule of MICAL1 (PubMed:27552051). Interacts with TBC1D13 (By similarity). Interacts with SEC16A (By similarity). Interacts with CHM and CHML (PubMed:29125462). Interacts with LRRK2; interaction facilitates phosphorylation of Thr-73 (PubMed:26824392). Interacts (when phosphorylated on Thr-73) with RILPL1 and RILPL2 (PubMed:30398148, PubMed:29125462).
