Anti-RHPN2 antibodies are used in the immunodetection of the protein rhophilin Rho GTPase binding protein 2. In humans, the canonical protein has a reported length of 686 amino acid residues and a mass of 77 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the RHPN protein family, RHPN2 is known to bind specifically to GTP-Rho. Synonyms for this target antigen include 76 kDa RhoB effector protein, GTP-Rho-binding protein 2, rhophilin-like Rho-GTPase binding protein, and rhophilin-2. RHPN2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RHPN2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
