Anti-DIRAS1 antibodies are used in the immunodetection of the protein DIRAS family GTPase 1. In humans, the canonical protein has a reported length of 198 amino acid residues and a mass of 22.3 kDa. Its subcellular localization is in the cell membrane. It is reported to be highly expressed in the heart and brain. A member of the Di-Ras protein family, DIRAS1 is known to be involved with signal transduction pathways. Synonyms for this target antigen include DIRAS family, GTP-binding RAS-like 1, distinct subgroup of the Ras family member 1, ras-related inhibitor of cell growth, small GTP-binding tumor suppressor 1, and GTP-binding protein Di-Ras1. DIRAS1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some DIRAS1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
