Anti-RRAS antibodies are used in the immunodetection of the protein RAS related. In humans, the canonical protein has a reported length of 218 amino acid residues and a mass of 23.5 kDa. Its subcellular localization is in the cell membrane. A member of the Ras protein family, rras is reported to regulate the organization of the actin cytoskeleton. Post-translational modifications have been described, including palmitoylation. Synonyms for this target antigen include ras-related protein R-Ras, oncogene RRAS, p23, ras family small GTP binding protein R-Ras, related RAS viral (r-ras) oncogene homolog, and RRAS1. RRAS gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species.
