Anti-RHOA antibodies are used in the immunodetection of the protein ras homolog family member A. In humans, the canonical protein has a reported length of 193 amino acid residues and a mass of 21.8 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. It is notably expressed in many tissues, such as the adrenal gland, urinary bladder, and adipose tissue. A member of the Rho protein family, RhoA is reported to be a Small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. Synonyms for this target antigen include ARHA, EDFAOB, RHO12, RHOH12, transforming protein RhoA, and ARH12. RHOA gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 920 citations in the literature describe the use of RhoA antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
