Enables hydroxymethylglutaryl-CoA reductase (NADPH) activity. Involved in ergosterol biosynthetic process. Located in endoplasmic reticulum membrane and nuclear envelope. Part of proteasome complex. Is active in endoplasmic reticulum. Human ortholog(s) of this gene implicated in several diseases, including attention deficit hyperactivity disorder; coronary artery disease (multiple); diabetes mellitus (multiple); muscular disease (multiple); and neurodegenerative disease (multiple). Orthologous to human HMGCR (3-hydroxy-3-methylglutaryl-CoA reductase).
SGD Description
HMG-CoA reductase; converts HMG-CoA to mevalonate, a rate-limiting step in sterol biosynthesis; one of two isozymes; overproduction induces assembly of peripheral ER membrane arrays and short nuclear-associated membrane stacks; forms foci at nuclear periphery upon DNA replication stress; primarily expressed on the peri-membrane side of the ER; human homolog HMGCR can complement yeast hmg2 mutant
