Protein Function  COX7A1 as a novel gene that might play a crucial role in the etiology of lung adenocarcinoma and can serve as a biomarker for lung cancer disease progression.
Biochemical Properties The utilization of oxygen by the mitochondria to generate energy is under the control of cytochrome c oxidase (complex IV or Cox) which consists of 13 subunits (10 encoded in the nuclear genome, 3 encoded in the mitochondrial genome).It has been proposed that Cox is the rate-limiting enzyme of the electron transport chain (ETC) and studies have revealed six isoforms of Cox subunits that are tissue specific and that potentially regulate energy production.

Additional Comments Deletion of the Cox7a1 isoform results in reduced muscle bioenergetics and hindlimb capillarity, helping to explain the observed impairment of muscle structure and function. Overexpression of COX7A1 in human lung cancer cells led to inhibition of cell proliferation and increase in cell death via apoptosis.
