7-Dehydrocholesterol reductase
7-dehydrocholesterol reductase, also known as DHCR7, is a protein that in humans is encoded by the ''DHCR7'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=1717 )〕 ==Function==
The protein encoded by this gene is an enzyme catalyzing the production of cholesterol from 7-Dehydrocholesterol using NADPH. The DHCR7 gene encodes delta-7-sterol reductase (EC 1.3.1.21), the ultimate enzyme of mammalian sterol biosynthesis that converts 7-dehydrocholesterol (7-DHC) to cholesterol. This enzyme removes the C(7-8) double bond introduced by the sterol delta8-delta7 isomerases. In addition, its role in drug-induced malformations is known: inhibitors of the last step of cholesterol biosynthesis such as AY9944 and BM15766 severely impair brain development.〔
