Predicted to enable cytochrome-c oxidase activity. Predicted to be involved in mitochondrial respirasome assembly and regulation of oxidative phosphorylation. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; heart; hemolymphoid system; integumental system; and nervous system. Orthologous to several human genes including COX7A2 (cytochrome c oxidase subunit 7A2). [provided by Alliance of Genome Resources, Apr 2022]
Ubiquitous expression in heart adult (RPKM 183.5), kidney adult (RPKM 165.8) and 28 other tissues See more

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.
