Post Translational Modifications N-glycosylated. Deglycosylated by NGLY1 on release from the endoplasmic reticulum (ER) in a sterol-mediated manner. Undergoes sterol-mediated ubiquitination and ER-associated degradation (ERAD). Accumulation of sterols in the endoplasmic reticulum (ER) membrane, triggers binding of the reductase to the ER membrane protein INSIG1 or INSIG2. The INSIG1 binding leads to the recruitment of the ubiquitin ligase, AMFR/gp78, RNF139 or RNF145, initiating ubiquitination of the reductase. The ubiquitinated reductase is then extracted from the ER membrane and delivered to cytosolic 26S proteosomes by a mechanism probably mediated by the ATPase Valosin-containing protein VCP/p97. The INSIG2-binding leads to the recruitment of the ubiquitin ligase RNF139, initiating ubiquitination of the reductase. Lys-248 is the main site of ubiquitination. Ubiquitination is enhanced by the presence of a geranylgeranylated protein. Phosphorylated. Phosphorylation at Ser-872 reduces the catalytic activity.
Function 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. HMGCR is the main target of statins, a class of cholesterol-lowering drugs.
