Cytochrome c oxidase copper chaperone COX11 (COX11)

Target
COX11
Molecular classification
Enzyme, Mitochondrial protein, Copper chaperone, Membrane protein
01

Overview

Cytochrome c oxidase copper chaperone COX11 is an essential mitochondrial inner membrane protein involved in the terminal assembly of the cytochrome c oxidase (Complex IV) of the mitochondrial respiratory chain. While not a structural subunit, COX11 facilitates the insertion of copper into the CuB site of subunit I, enabling proper enzymatic activity and electron transfer from cytochrome c to oxygen. Disease associations include mitochondrial complex IV deficiency, with potential clinical manifestations like epilepsy[1][2][3][5][6].
