Anti-RAB31 antibodies are used in the immunodetection of the protein RAB31, member RAS oncogene family. In humans, the canonical protein has a reported length of 194 amino acid residues and a mass of 21.6 kDa. Its subcellular localization is in the cytoplasmic vesicles and Golgi. It is reported to be highly expressed in the placenta and brain with lower levels in the heart and lung. A member of the Rab protein family, RAB31 is known to be involved with insulin signaling pathways and intracellular protein transport. Synonyms for this target antigen include ras-related protein Rab-31, ras-related protein Rab-22B, and Rab22B. RAB31 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of RAB31 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.
