Anti-RAB39A antibodies are used in the immunodetection of the protein RAB39A, member RAS oncogene family. In humans, the canonical protein has a reported length of 217 amino acid residues and a mass of 25 kDa. Its subcellular localization is in the cytoplasmic vesicles, lysosomes, and cell membrane. A member of the Rab protein family, RAB39A is reported to play a role in the maturation and acidification of phagosomes that engulf pathogens, such as S.aureus and M.tuberculosis. Synonyms for this target antigen include RAB39, ras-related protein Rab-39A, RAB39, member RAS oncogene family, rab-39, rab-related GTP-binding protein, and K28. RAB39A gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some RAB39A 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.
