enzyme of the cholesterol biosynthetic pathway, mutations are associated with Conradi-Huenermann syndrome. 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
