  • One of two isozymes of HMG-CoA reductase that catalyzes the conversion of HMG-CoA to mevalonate, which is a rate-limiting step in sterol biosynthesis; localizes to the nuclear envelope; overproduction induces the formation of karmellae [SGD]
    • Organism: Saccharomyces cerevisiae
    Length: 1054 amino acids

    Gene Ontology:
    Cellular Component: nuclear envelope [IDALink to PubMed article]
    endoplasmic reticulum membrane [IDALink to PubMed article]
    mitochondrial matrix [TAS]
    Biological Process: ergosterol biosynthetic process [TAS]
    Molecular Function: hydroxymethylglutaryl-CoA reductase (NADPH) activity [TAS]
