    Summary
    Enables oxidoreductase activity, acting on NAD(P)H, heme protein as acceptor. Involved in heme A biosynthetic process. Located in mitochondrial inner membrane. Used to study ovarian dysfunction. Human ortholog(s) of this gene implicated in Leigh disease; hypertrophic cardiomyopathy; and mitochondrial complex IV deficiency nuclear type 6. Orthologous to human COX15 (cytochrome c oxidase assembly homolog COX15). [provided by Alliance of Genome Resources, Dec 2024]

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. findings reveal that Cox15 not only associates with respiratory supercomplexes, but also interacts with the cytochrome bc 1 dimer even in the absence of cytochrome c oxidase.
      Title: Cox15 interacts with the cytochrome bc(1) dimer within respiratory supercomplexes as well as in the absence of cytochrome c oxidase.
    2. Shy1 does not serve as a mobile heme carrier between the heme a synthase and maturing Cox1 but rather cooperates with Cox15 for heme transfer and insertion in early assembly intermediates of cytochrome c oxidase.
      Title: The heme a synthase Cox15 associates with cytochrome c oxidase assembly intermediates during Cox1 maturation.
    3. COX10, the physiological partner of COX15, does not share the same regulatory mechanism with COX15
