Rab20 Proteins and Enzymes

RAB20, also known as Ras-related protein Rab-20, is a 234 amino acid protein that is 26 kDa, belongs to the small GTPase superfamily, expressed in 15 of 18 exocrine pancreatic adenocarcinomas, plays a role in apical endocytosis/recycling, maturation and acidification of phagosomes that engulf pathogens such as S.aureus and M.tuberculosis, and in the fusion of phagosomes with lysosomes. This protein is currently being studied for its involvement in hemophagocytic lymphohistiocytosis, pancreatic carcinoma, pancreatitis, adenocarcinoma, and carcinoma. RAB20 protein has interactions with SMURF1, SMAD4 and TGFBR1 in Epithelial Tight Junctions pathway.
