Ras-related protein Rab-11B is a protein that in humans is encoded by the RAB11B gene. Rab11b is reported as most abundantly expressed in brain, heart and testes. Rab (Ras-related in brain) proteins form the largest section of the Ras superfamily of small GTPases. The Rab family proteins regulate intracellular membrane trafficking processes including vesicle budding, tethering, and fusion. The isoforms Rab11a, Rab11b, and Rab11c/Rab25 constitute the Rab11 subfamily based on specific sequence motifs. While RAB11A is located on chromosome 15 and RAB11C on chromosome 1, RAB11B is placed on chromosome 19. Rab11 proteins are implicated in endocytosis and exocytosis. Rab11b is reported as most abundantly expressed in brain, heart and testes. Early studies with deletions of RAB11 homologs in Sacc

| - Ras-related protein Rab-11B is a protein that in humans is encoded by the RAB11B gene. Rab11b is reported as most abundantly expressed in brain, heart and testes. Rab (Ras-related in brain) proteins form the largest section of the Ras superfamily of small GTPases. The Rab family proteins regulate intracellular membrane trafficking processes including vesicle budding, tethering, and fusion. The isoforms Rab11a, Rab11b, and Rab11c/Rab25 constitute the Rab11 subfamily based on specific sequence motifs. While RAB11A is located on chromosome 15 and RAB11C on chromosome 1, RAB11B is placed on chromosome 19. Rab11 proteins are implicated in endocytosis and exocytosis. Rab11b is reported as most abundantly expressed in brain, heart and testes. Early studies with deletions of RAB11 homologs in Saccharomyces cerevisiae proved their importance in cell survival.Despite sharing high sequence homology, Rab11a and Rab11b appear to reside within distinct vesicle compartments. Majority of Rab11b neither colocalize with transferrin receptor nor with the polymeric IgA receptor. This protein also exhibits a dependence on the microtubule cytoskeleton that is different from Rab11a. High sequence diversity in the C-terminal hypervariable region is responsible for variable membrane targeting between these proteins. (en)
