Brief Description & Uses

100 g of monoclonal antibody reactive against the 33 kDa complex IV assembly factor SURF1. Cellular levels of SURF1 are highest in growing cultured cells.

SURF1 is an important assembly factor for cytochrome c oxidase which is thought to participate in the folding of subunit II and parallel Cu2+ insertion into this subunit. Mutations of SURF1, particularly ones that result in an absence or near absence of the polypeptide, are the leading cause of cytochrome c oxidase deficiency.

The anti-SURF1 mAb reacts specifically in human and bovine tissues. The protein is easily detected in cells rapidly dividing their mitochondria and has the highest levels in cells impaired in COX assembly. The levels of SURF1 are always low and in some cases neglible, even in rapidly dividing fibroblast cell cultures. Levels are lowest in mature tissues such as heart or liver; the levels of SURF1 are in fact so low that a large amount of tissue material must be used that the specificity is not as good as in cells. The low copy number is consistent with it acting to catalyze Complex IV assembly. In cells where cytochrome c oxidase assembly is incomplete because of mutations in genes for structural subunits of the enzyme SURF1 is significantly over-expressed. This is evident in Rho0 fibroblasts which are missing mtDNA and hence cannot synthesize subunits I, II and III of cytochrome c oxidase.
