Summaries for COX7A2 Gene

Entrez Gene Summary for COX7A2 Gene

  • Cytochrome c oxidase, the terminal component of the mitochondrial respiratory chain, catalyzes the electron transfer from reduced cytochrome c to oxygen. This component is a heteromeric complex consisting of three catalytic subunits encoded by mitochondrial genes, and multiple structural subunits encoded by nuclear genes. The mitochondrially-encoded subunits function in electron transfer, while the nuclear-encoded subunits may function in the regulation and assembly of the complex. This nuclear gene encodes polypeptide 2 (liver isoform) of subunit VIIa, with this polypeptide being present in both muscle and non-muscle tissues. In addition to polypeptide 2, subunit VIIa includes polypeptide 1 (muscle isoform), which is present only in muscle tissues, and a related protein, which is present in all tissues. Alternative splicing results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 4 and 14. [provided by RefSeq, Oct 2009]

GeneCards Summary for COX7A2 Gene

COX7A2 (Cytochrome C Oxidase Subunit 7A2) is a Protein Coding gene. Diseases associated with COX7A2 include Barrett's Adenocarcinoma and Esophagus Adenocarcinoma. Among its related pathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. and Cardiac muscle contraction. GO annotations related to this gene include electron carrier activity and cytochrome-c oxidase activity. An important paralog of this gene is COX7A1.
