Anti-GTPBP4 antibodies are used in the immunodetection of the protein GTP binding protein 4. In humans, the canonical protein has a reported length of 634 amino acid residues and a mass of 74 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. A member of the OBG GTPase protein family, gtpbp4 is reported to be involved in biogenesis of the 60S ribosomal subunit. Synonyms for this target antigen include NGB, NOG1, G protein-binding protein CRFG, GTP-binding protein NGB, chronic renal failure gene protein, and CRFG. GTPBP4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of gtpbp4 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
