Anti-TTC19 antibodies are used in the immunodetection of the protein tetratricopeptide repeat domain 19. In humans, the canonical protein has a reported length of 380 amino acid residues and a mass of 42.5 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. A member of the TTC19 protein family, TTC19 is known to be required for the preservation of the structural and functional integrity of mitochondrial respiratory complex III by allowing the physiological turnover of the Rieske protein UQCRFS1. The TTC19 gene has been associated with the disease, Mitochondrial complex III deficiency. Synonyms for this target antigen include MC3DN2, tetratricopeptide repeat protein 19, mitochondrial, TPR repeat protein 19, and 2010204O13Rik. TTC19 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the TTC19 antibodies listed below. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
