Anti-RAB43 antibodies are used in the immunodetection of the protein RAB43, member RAS oncogene family. In humans, the canonical protein has a reported length of 212 amino acid residues and a mass of 23.3 kDa. Its subcellular localization is in the cytoplasmic vesicles and Golgi. Up to 3 different isoforms have been reported for this protein. It is found to be widely expressed in the brain, testis, lung, heart, ovary, colon, kidney, uterus and spleen but not in the liver. A member of the Rab protein family, RAB43 is known to be involved with Golgi organization and intracellular protein transport. Synonyms for this target antigen include ras-related protein Rab-43 and ras-related protein Rab-41. RAB43 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RAB43 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
