Anti-ATP5IF1 antibodies are used in the immunodetection of the protein ATP synthase inhibitory factor subunit 1. In humans, the canonical protein has a reported length of 106 amino acid residues and a mass of 12.2 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the ATPase inhibitor protein family, ATP5IF1 is known to be involved with angiogenesis and erythrocyte differentiation. Synonyms for this target antigen include ATP synthase inhibitor protein, ATPase inhibitor protein, ATPase inhibitory factor 1, IF(1), IF1, and ATPase inhibitor, mitochondrial. ATP5IF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ATP5IF1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
