Cytochrome b-c1 complex subunit 2, mitochondrial precursor recombinant protein epitope signature tag (PrEST)


Anti-UQCRC2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit

Biochem/physiol Actions

UQCRC2 (ubiquinol-cytochrome c reductase core protein II) gene encodes a subunit of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex) that functions in complex assemble. This complex forms part of the mitochondrial respiratory chain and functions in electron transfer from ubiquinol to cytochrome c. The core II subunit is encoded by a nuclear gene, which is mapped to human chromosome 16p12. Defects in this gene cause Mitochondrial complex III deficiency characterized by mitochondrial encephalopathy, psychomotor retardation, ataxia, severe failure to thrive, liver dysfunction, renal tubulopathy, muscle weakness and exercise intolerance.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST86635.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
