Anti-RAB13 antibodies are used in the immunodetection of the protein RAB13, member RAS oncogene family. In humans, the canonical protein has a reported length of 203 amino acid residues and a mass of 22.8 kDa. Its subcellular localization is in the cytoplasmic vesicles, Golgi, and cell membrane. It is notably expressed in several types of epithelia, including intestine, kidney, liver and in endothelial cells. A member of the Rab protein family, RAB13 is known to be involved with insulin signaling pathways and cytoskeleton organization. Synonyms for this target antigen include ras-related protein Rab-13, RAS-associated protein RAB13, cell growth-inhibiting gene 4 protein, growth-inhibiting gene 4 protein, and GIG4. RAB13 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of RAB13 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
