The small GTPases Rab are key regulators of intracellular mbrane trafficking, from the formation of transport vesicles to their fusion with mbranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to mbranes different set of downstream effectors directly responsible for vesicle formation, movent, tethering and fusion. That Rab regulates endocytic recycling. Acts as a major regulator of mbrane delivery during cytokinesis. Together with MYO5B and RAB8A participates in epithelial cell polarization. Together with RAB3IP, RAB8A, the exocyst complex, PARD3, PRKCI, ANXA2, CDC42 and DNMBP promotes transcytosis of PODXL to the apical mbrane initiation sites (AMIS), apical surface formation and lumenogenesis. Together with MYO5B participates in CFTR trafficking to the plasma mbrane and TF (Transferrin) recycling in nonpolarized cells. Required in a complex with MYO5B and RAB11FIP2 for the transport of NPC1L1 to the plasma mbrane. Participates in the sorting and basolateral transport of CDH1 from the Golgi apparatus to the plasma mbrane. Regulates the recycling of FCGRT (receptor of Fc region of monomeric Ig G) to basolateral mbranes. May also play a role in melanosome transport and release from melanocytes.
