Summary: Predicted to enable 3-demethoxyubiquinol 3-hydroxylase activity and chromatin binding activity. Acts upstream of or within several processes, including chordate embryonic development; determination of adult lifespan; and mitochondrial ATP synthesis coupled electron transport. Located in mitochondrion. Is expressed in several structures, including alimentary system; ear; heart; respiratory system; and skeleton. Human ortholog(s) of this gene implicated in autosomal recessive distal hereditary motor neuronopathy 9 and primary coenzyme Q10 deficiency 8. Orthologous to human COQ7 (coenzyme Q7, hydroxylase).

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.
