RAB11A (P62491) - Overview - Molecular Target Synopsis

Protein


RAB11A, Ras-related protein Rab-11A
UniProt P62491

Also Known as RB11A_HUMAN, RAB11A, RAB11

The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. 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. That Rab regulates endocytic recycling. Acts as a major regulator of membrane 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 membrane initiation sites (AMIS), apical surface formation and lumenogenesis. Together with MYO5B participates in CFTR trafficking to the plasma membrane and TF (Transferrin) recycling in nonpolarized cells. Required in a complex with MYO5B and RAB11FIP2 for the transport of NPC1L1 to the plasma membrane. Participates in the sorting and basolateral transport of CDH1 from the Golgi apparatus to the plasma membrane. Regulates the recycling of FCGRT (receptor of Fc region of monomeric Ig G) to basolateral membranes. May also play a role in melanosome transport and release from melanocytes. Interacts with RIP11 and STXBP6. Interacts with SGSM1, SGSM2 and SGSM3 (By similarity). Interacts with EXOC6 in a GTP-dependent manner (By similarity). Interacts with RAB11FIP1, RAB11FIP2, RAB11FIP3 (via its C-terminus) and RAB11FIP4. Interacts with EVI5; EVI5 and RAB11FIP3 may be mutually exclusive and compete for binding RAB11A. Interacts with VIPAS39. Interacts with MYO5B. Found in a complex with MYO5B and CFTR. Interacts with NPC1L1. Interacts (GDP-bound form) with ZFYVE27 (PubMed:21976701, PubMed:17082457). Interacts with BIRC6/bruce. May interact with TBC1D14. Interacts with UNC119; in a cell cycle-dependent manner. GDP-bound and nucleotide-free forms interact with SH3BP5 (PubMed:26506309, PubMed:30217979). Interacts (GDP-bound form) with KIF5A in a ZFYVE27-dependent manner (PubMed:21976701). Interacts (GDP-bound form) with RELCH (By similarity). Found in a complex composed of RELCH, OSBP1 and RAB11A.
