Anti-GTPBP3 antibodies are used in the immunodetection of the protein GTP binding protein 3, mitochondrial. In humans, the canonical protein has a reported length of 492 amino acid residues and a mass of 52.1 kDa. Its subcellular localization is in the mitochondria. Up to 4 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. It is a member of the TrmE GTPase protein family. The GTPBP3 gene has been associated with the disease, Combined oxidative phosphorylation deficiency. Synonyms for this target antigen include tRNA modification GTPase GTPBP3, mitochondrial and mitochondrial GTP-binding protein 1. GTPBP3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GTPBP3 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.
