Rab11A (RAB11A Member RAS Oncogene Family, Rab-11A, MGC1490, RAB11, Rab-11, Ras-related Protein Rab-11A, Ras-related protein Rab11A, YL8)
Description:
Rab proteins are low-molecular-weight GTP-binding proteins that form the largest branch of the Ras superfamily of GTPases. Located on the cytoplasmic face of organelles and vesicles, rab proteins are involved in intracellular membrane fusion reactions. Three membrane proteins, synaptosomal associated protein of 25kD (SNAP-25), synaptobrevin, and syntaxin, form the core of a ubiquitous membrane fusion machine that interacts with the soluble proteins N-ethylmaleimide-sensitive factor (NSF) and a-SNAP. Rab proteins, in coordination with the core fusion machinery and Munc-18, help to mediate vesicle docking and fusion. There exist over 40 Rab proteins that have been described in mammals. Rab 11 is a known marker for protein trafficking, sorting, and recycling in the endosomal pathway. Rab11 is a member of the YPT-1 subfamily of Ras-related GTP-binding proteins. Rab11 mRNA has been detected in a variety of tissues including brain, testis, spleen, heart and gastrointestinal mucosa. In the gastric fundus the Rab11 protein is expressed in parietal cell tubulovesicles membranes. Expression of the Rab11 protein appears to occur in discrete epithelial cell populations where it localizes to apical vesicular populations.
