The enzyme may be involved in liver function, since the mRNA is only detected in hepatocytes not in connective tissue or blood vessels. The expression of the SI gene is regulated transcriptionally in vitro and in vivo by widely known regulatory agents ranging from tamoxifen, an oestrogen receptor antagonist and SI-specific inhibitor, to cholesterol-lowering drugs Rattus norvegicus ? - ? 370718 5.3.3.5 5alpha-cholesta-8,24-dien-3beta-ol - Homo sapiens 5alpha-cholesta-7,24-dien-3beta-ol - ? 399747 5.3.3.5 cholest-8-enol - Homo sapiens cholest-7-enol - ? 368685 5.3.3.5 cholesta-8,24-dien-3beta-ol - Zea mays ? - ? 400665 5.3.3.5 DELTA8-sitostenol - Zea mays stigmast-7-en-3beta-ol - ? 400827 5.3.3.5 dihydrozymosterol - Homo sapiens lathosterol - ? 400849 5.3.3.5 fecosterol - Homo sapiens 24-methylene-5alpha-cholest-7-en-3beta-ol - ? 368686 5.3.3.5 additional information 3-desoxyzymosterol is not an active substrate Homo sapiens ? - ? 89 5.3.3.5 additional information 4,4-dimethyl-cholesta-8,24-dien-3beta-ol, 4,4-dimethyl-ergosta-8,24-dien-3beta-ol, 4alpha,14aloha-dimethyl-ergosta-8,24-dien-3beta-ol, and cholest-8(14)-en-3beta-ol are no substrates Zea mays ? - ? 89 5.3.3.5 stigmasta-8-en-3beta-ol - Zea mays ? - ? 401923 5.3.3.5 zymostenol - Homo sapiens lathosterol - ? 427573 5.3.3.5 zymostenol - Saccharomyces cerevisiae lathosterol - ? 427573 5.3.3.5 zymostenol - Yarrowia lipolytica lathosterol - ? 427573 5.3.3.5 zymostenol - [Candida] glabrata lathosterol - ? 427573 5.3.3.5 zymosterol - Homo sapiens cholesta-7,24-dienol - ? 368684 5.3.3.5 zymosterol - Saccharomyces cerevisiae cholesta-7,24-dienol - ? 368684 5.3.3.5 zymosterol - Zea mays cholesta-7,24-dienol - ? 368684 5.3.3.5 zymosterol preferred substrate for DELTA7-sterol production, the reaction equilibrium for double-bond isomerization favours the forward direction, DELTA8 to DELTA7 Homo sapiens cholesta-7,24-dienol - r 368684 5.3.3.5 zymosterol primary substrate Homo sapiens cholesta-7,24-dienol - ? 368684 5.3.3.5 zymosterol primary substrate Saccharomyces cerevisiae cholesta-7,24-dienol - ? 368684 5.3.3.5 zymosterol primary substrate Yarrowia lipolytica cholesta-7,24-dienol - ? 368684 5.3.3.5 zymosterol primary substrate [Candida] glabrata cholesta-7,24-dienol - ? 368684
