    Functioni

    May function in mitochondrial tRNA maturation. Catalyzes the beta-oxidation at position 17 of androgens and estrogens, and has 3-alpha-hydroxysteroid dehydrogenase activity with androsterone. Catalyzes the third step in the beta-oxidation of fatty acids. Carries out oxidative conversions of 7-beta-hydroxylated bile acids. Also exhibits 20-beta-OH and 21-OH dehydrogenase activities with C21 steroids. Required for cell survival during embryonic development. May play a role in germline formation.2 Publications

    Pathology & Biotechi

    Disruption phenotypei

    Embryonic and pupal lethal. Male mutants show small testes and degenerating spermatocytes with a large accumulation of small fat-containing vesicles in the cytoplasm and almost no mitochondria. Null mutant photoreceptors fail to differentiate normally, are unable to form proper rhabdomeres and present smaller mitochondria with fewer, but swollen crestae, than wild-type cells.1 Publication
