Bioinformation

Database Links	GeneID: 3156 Human HMGCR Swiss-port # P04035 Human 3-hydroxy-3-methylglutaryl-coenzyme A reductase
Gene Symbol	HMGCR
Gene Full Name	3-hydroxy-3-methylglutaryl-CoA reductase
Background	HMG-CoA reductase is the rate-limiting enzyme for cholesterol synthesis and is regulated via a negative feedback mechanism mediated by sterols and non-sterol metabolites derived from mevalonate, the product of the reaction catalyzed by reductase. Normally in mammalian cells this enzyme is suppressed by cholesterol derived from the internalization and degradation of low density lipoprotein (LDL) via the LDL receptor. Competitive inhibitors of the reductase induce the expression of LDL receptors in the liver, which in turn increases the catabolism of plasma LDL and lowers the plasma concentration of cholesterol, an important determinant of atherosclerosis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]
Function	Transmembrane glycoprotein that is the rate-limiting enzyme in cholesterol biosynthesis as well as in the biosynthesis of nonsterol isoprenoids that are essential for normal cell function including ubiquinone and geranylgeranyl proteins. [UniProt]
Cellular Localization	Endoplasmic reticulum membrane; Multi-pass membrane protein. [UniProt]
Calculated MW	97 kDa
PTM	N-glycosylated. Deglycosylated by NGLY1 on release from the endoplasmic reticulum (ER) in a sterol-mediated manner. Undergoes sterol-mediated ubiquitination and ER-association degradation (ERAD). Accumulation of sterols in the endoplasmic reticulum (ER) membrane, triggers binding of the reductase to the ER membrane protein INSIG1. This INSIG1 binding leads to the recruitment of the ubiquitin ligase, AMFR/gp78, 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. Lys-248 is the main site of ubiquitination. Ubiquitination is enhanced by the presence of a geranylgeranylated protein. [UniProt]
