The ratio of the 17,20 lyase to 17alpha-hydroxylase activity of P450c17 determines the ratio of C21 to C19 steroids produced. This ratio is regulated post-translationally by at least three factors: the abundance of the electron-donating protein P450 oxidoreductase, the presence of cytochrome b(5), and the serine phosphorylation of P450c17. Study of these and related factors may yield important information about the pathophysiology of adrenarche and the polycystic ovary syndrome (PCOS)."; prov:wasQuotedFrom pubmed:12573809 . sub:_5 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:12573809; prov:wasDerivedFrom beldoc:, sub:_4 . } sub:pubinfo { this: dct:created "2014-07-03T14:30:09.909+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
