Anti-RP2 antibodies are used in the immunodetection of the protein RP2 activator of ARL3 GTPase. In humans, the canonical protein has a reported length of 350 amino acid residues and a mass of 39.6 kDa. Its subcellular localization is in the cell membrane. It is ubiquitously expressed across many tissue types. A member of the TBCC protein family, RP2 is known to act as a GTPase-activating protein (GAP) involved in trafficking between the Golgi and the ciliary membrane. Post-translational modifications have been described, including palmitoylation and myristoylation. The RP2 gene has been associated with the disease, Retinitis pigmentosa. Synonyms for this target antigen include NM23-H10, NME10, TBCCD2, XRP2, protein XRP2, and DELXp11.3. RP2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RP2 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.
