Summaries for COX14 Gene

Entrez Gene Summary for COX14 Gene

  • This gene encodes a small single-pass transmembrane protein that localizes to mitochondria. This protein may play a role in coordinating the early steps of cytochrome c oxidase (COX; also known as complex IV) subunit assembly and, in particular, the synthesis and assembly of the COX I subunit of the holoenzyme. Mutations in this gene have been associated with mitochondrial complex IV deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

GeneCards Summary for COX14 Gene

COX14 (COX14, Cytochrome C Oxidase Assembly Factor) is a Protein Coding gene. Diseases associated with COX14 include Mitochondrial Complex Iv Deficiency and Muscular Dystrophy, Congenital, Megaconial Type. Among its related pathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. and Gene Expression.

UniProtKB/Swiss-Prot for COX14 Gene

  • Core component of the MITRAC (mitochondrial translation regulation assembly intermediate of cytochrome c oxidase complex) complex, that regulates cytochrome c oxidase assembly. Requires for coordination of the early steps of cytochrome c oxidase assembly with the synthesis of MT-CO1.
