Anti-FASTKD3 antibodies are used in the immunodetection of the protein FAST kinase domains 3. In humans, the canonical protein has a reported length of 662 amino acid residues and a mass of 75.7 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. A member of the FAST kinase protein family, FASTKD3 is reported to be required for normal mitochondrial respiration. Synonyms for this target antigen include FAST kinase domain-containing protein 3, mitochondrial. FASTKD3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some FASTKD3 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.
