Structure and Function:
|
This protein is subunit 4 of the cytochrome c oxidase complex, which catalyzes the reduction of O2 to H2O as the final oxidase complex of the respiratory chain.
|
|
Disease Associations:
|
Genetic alterations of this enzyme complex are a common cause of OXPHOS diseases and the enzyme is altered in patients with Alzheimer’s disease.

Figure 2. Skeletal muscle immunohistochemistry using MS408- fixed frozen tissue sections from a patient with a single large deletion of the mtDNA. All muscle fibers express subunit IV of complex IV because this subunit is encoded by nuclear DNA and persists in a partial complex in the absence of mtDNA-encoded subunits. Image kindly provided by Dr. J. Murphy and D. Turnbull, Mitochondrial Research Group, Newcastle University.

Colon immunohistochemistry tissue sections from a normal ageing patient show complex IV negative crypts due to clonal expansion of colonic stem cells bearing mutations in mtDNA that affect expression of complex IV.

Figure 4. Mitochondrial localization of complex IV in normal human fibroblasts visualized by immunocytochemistry using anti-complex IV subunit IV mAb 10G8D12C12 (MS408). Cultured human embryonic lung-derived fibroblasts (strain MRC5) were fixed, permeabilized and then labeled with MS408 (10 µg/ml) followed by an AlexaFluor® 488-conjugated-goat-anti-mouse IgG2a isotype specific secondary antibody (1 µg/ml)
