Anti-TACO1 antibodies are used in the immunodetection of the protein translational activator of cytochrome c oxidase I. In humans, the canonical protein has a reported length of 297 amino acid residues and a mass of 32.5 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. A member of the TACO1 protein family, TACO1 is known to act as a translational activator of mitochondrially-encoded cytochrome c oxidase 1. The TACO1 gene has been associated with the disease, Mitochondrial complex IV deficiency. Synonyms for this target antigen include MC4DN8, translational activator of cytochrome c oxidase 1, clone HQ0477 PRO0477p, coiled-coil domain-containing protein 44, and CCDC44. TACO1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of TACO1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
