Anti-FASTKD1 antibodies are used in the immunodetection of the protein FAST kinase domains 1. In humans, the canonical protein has a reported length of 847 amino acid residues and a mass of 97.4 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the FAST kinase protein family, FASTKD1 is reported to be involved in down-regulation of mitochondrial MT-ND3 mRNA levels which leads to decreased respiratory complex I abundance and activity. Synonyms for this target antigen include FAST kinase domain-containing protein 1, mitochondrial. FASTKD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some FASTKD1 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.
