Rab11A also known as Ras-related protein Rab-11A is a member of the Rab family of small GTPases. This protein has a molecular weight of about 24.7 kDa and plays an important role in the regulation of intracellular recycling pathways. Rab11A is widely expressed in various tissues including the brain liver heart and lungs. It is found on recycling endosomes where it orchestrates vesicle trafficking a process critical for maintaining cellular homeostasis.
Biological function summary

Rab11A functions in intracellular transport by regulating vesicle budding and fusion. It ensures the proper recycling of membrane proteins like transferrin receptors and integrins. Rab11A interacts with a set of effector proteins that guide vesicle movement towards specific locations within the cell. This protein can also form complexes with other proteins such as Rab11FIP1 to facilitate effective cargo delivery. The actions of Rab11A are critical in processes like cell migration and growth factor signaling.

Pathways

Rab11A plays a role in the endocytic recycling and exocytic pathways. It ensures proper trafficking from endosomes to the plasma membrane. Rab11A interacts closely with proteins like Rab5 and Rab7 setting up a sequential transport system that regulates cargo delivery between different organelles. In the recycling pathway Rab11A is important for the sorting and return of cell surface receptors to the plasma membrane helping to maintain cell surface receptor pools.

Rab11A links to cancer and neurodegenerative diseases. Altered Rab11A expression and activity can affect processes like cell proliferation and apoptosis contributing to tumorigenesis. In neurodegenerative diseases aberrant Rab11A-mediated recycling may impact neurotrophic signaling and axonal transport leading to neuronal dysfunction. Mutations or dysregulation in related proteins such as Rab11FIP further implicate Rab11A in these diseases as they can disrupt the normal physiological functions governed by Rab11A.

General info

Function

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 (PubMed : 15601896, PubMed : 15689490, PubMed : 17462998, PubMed : 19542231, PubMed : 20026645, PubMed : 20890297, PubMed : 21282656). The small Rab GTPase RAB11A regulates endocytic recycling (PubMed : 20026645). Forms a functional Rab11/FIP3/dynein complex that regulates the movement of peripheral sorting endosomes (SE) along microtubule tracks toward the microtubule organizing center/centrosome, generating the endosomal recycling compartment (ERC) (PubMed : 20026645). Acts as a major regulator of membrane delivery during cytokinesis (PubMed : 15601896). 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 (PubMed : 15689490, PubMed : 17462998, PubMed : 19542231, PubMed : 20890297, PubMed : 21282656). Promotes Rabin8/RAB3IP preciliary vesicular trafficking to mother centriole by forming a ciliary targeting complex containing Rab11, ASAP1, Rabin8/RAB3IP, RAB11FIP3 and ARF4, thereby regulating ciliogenesis initiation (PubMed : 25673879, PubMed : 31204173). On the contrary, upon LPAR1 receptor signaling pathway activation, interaction with phosphorylated WDR44 prevents Rab11-RAB3IP-RAB11FIP3 complex formation and cilia growth (PubMed : 31204173). Participates in the export of a subset of neosynthesized proteins through a Rab8-Rab10-Rab11-endososomal dependent export route via interaction with WDR44 (PubMed : 32344433).
