Structure, Expression, and Regulation of UDP-GlcNAc: Dolichol Phosphate GlcNAc-1-Phosphate Transferase (DPAGT1)
Abstract:Glycosylation of proteins on asparagine amino acids (N-linked) in proteins of eukaryotic cells is initiated by the biosynthesis of dolichol-pyrophosphate-N-acetylglucosamine from dolichol-phosphate and UDP-N-acetylglucosamine. The enzyme catalyzing this reaction, UDP-GlcNAc:Dolichol Phosphate GlcNAc-1-Phosphate Transferase (DPAGT1), has been further characterized in several cell types with respect to its gene, gene products, membrane topology, functional sites, lipid dependence, and metabolic regulation. This review summarizes these properties as an update from an earlier detailed and critical review by Lehrman (Lehrman, M. A. (1991) Glycobiology, 1, 553-562).

- Current Drug Targets aims to cover the latest and most outstanding developments on the medicinal chemistry and pharmacology of molecular drug targets e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will be devoted to a single timely topic, with series of in-depth reviews, written by leaders in the field, covering a range of current topics on drug targets. These issues will be organized and led by a guest editor who is a recognized expert in the overall topic. As the discovery, identification, characterisation and validation of novel human drug targets for drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
