Anti-UQCRC1 antibodies are used in the immunodetection of the protein ubiquinol-cytochrome c reductase core protein 1. In humans, the canonical protein has a reported length of 480 amino acid residues and a mass of 52.6 kDa. Its subcellular localization is in the mitochondria. It is reported to be expressed in the brain, including substantia nigra, striatum, cortex and cerebellum, and in spinal cord, heart, kidney, liver and muscle. A member of the Peptidase M16 protein family, UQCRC1 is a known component of the ubiquinol-cytochrome c oxidoreductase, a multisubunit transmembrane complex that is part of the mitochondrial electron transport chain which drives oxidative phosphorylation. Synonyms for this target antigen include PKNPY, QCR1, UQCR1, cytochrome b-c1 complex subunit 1, mitochondrial, complex III subunit 1, and D3S3191. UQCRC1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 170 citations in the literature describe the use of UQCRC1 antibodies in research. Western Blot is a widely used application for these antibodies. Flow Cytometry and Immunohistochemistry are also common applications.
