Anti-PTCD1 antibodies are used in the immunodetection of the protein pentatricopeptide repeat domain 1. In humans, the canonical protein has a reported length of 700 amino acid residues and a mass of 78.9 kDa. Its subcellular localization is in the mitochondria. It is notably expressed in testes, skeletal muscle and heart. A member of the PTCD1 protein family, PTCD1 is known to be involved with mitochondrial translation. Synonyms for this target antigen include pentatricopeptide repeat-containing protein 1, mitochondrial. PTCD1 gene orthologs have been reported in the mouse, rat, bovine and chicken species. Some PTCD1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunofluorescence are also common applications.
