Cytochrome c oxidase hypoxia associated subunit FA4L2 is a protein that in humans is encoded by the COXFA4L2gene (previously NDUFA4L2). COXFA4L2 is a mitochondrial protein that inhibits and regulates the electron transport chain, and is involved in the cellular response to hypoxia.
Structure
The COXFA4L2 gene is located on the long q arm of chromosome 12 at position 13.3 and it spans 5,860 base pairs.
