DESCRIPTION

Also known as HMDH_HUMAN, HMGCR. Catalyzes the conversion of (3S)-hydroxy-3-methylglutaryl-CoA (HMG-CoA) to mevalonic acid, the rate-limiting step in the synthesis of cholesterol and other isoprenoids, thus plays a critical role in cellular cholesterol homeostasis (PubMed:2991281, PubMed:21357570, PubMed:6995544). HMGCR is the main target of statins, a class of cholesterol-lowering drugs (PubMed:11349148, PubMed:18540668). Homotetramer (PubMed:10698924). Homodimer (PubMed:10698924). Interacts (via its SSD) with INSIG1; the interaction, accelerated by sterols, leads to the recruitment of HMGCR to AMFR/gp78 for its ubiquitination by the sterol-mediated ERAD pathway (PubMed:12535518, PubMed:19458199). Interacts with UBIAD1 (PubMed:23169578).
