Protein Name: Cytochrome c oxidase subunit 2

UniprotKB/SwissProt ID: COX2_HUMAN (P00403)

Gene Name: MT-CO2

Synonyms: COII, COXII, MTCO2

Organism: Homo sapiens (Human).

Function: Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1- 3 form the functional core of the enzyme complex. Subunit 2 transfers the electrons from cytochrome c via its binuclear copper A center to the bimetallic center of the catalytic subunit 1.

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Mitochondrion inner membrane; Multi-pass membrane protein.
