Ras-related protein Rab-10 (RAB10)

The little GTPases Rab are crucial regulators of intracellular membrane trafficking, from the formation of transport vesicles to their combination with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that's able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, motion, tethering and fusion (By similarity).

That Rab is mostly involved in the biosynthetic transport of proteins from the Golgi to the plasma membrane. Regulates, for instance, SLC2A4/GLUT4 glucose transporter-enriched vesicles delivery to the plasma membrane.
