Anti-ATP5F1D antibodies are used in the immunodetection of the protein ATP synthase F1 subunit delta. In humans, the canonical protein has a reported length of 168 amino acid residues and a mass of 17.5 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. It is a member of the ATPase epsilon chain protein family. The ATP5F1D gene has been associated with the disease, Mitochondrial complex V deficiency. Synonyms for this target antigen include MC5DN5, ATP synthase subunit delta, mitochondrial, ATP synthase, H+ transporting, mitochondrial F1 complex, delta subunit, F-ATPase delta subunit, and ATP5D. ATP5F1D gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ATP5F1D antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
