Predicted to be involved in mitochondrial cytochrome c oxidase assembly. Located in mitochondrion. Is expressed in heart ventricle; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in fatal infantile cardioencephalomyopathy due to cytochrome c oxidase deficiency 3. Orthologous to human COA5 (cytochrome c oxidase assembly factor 5).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
