    text
  • localizes to the cytosol, in agreement with its role in cytosolic synthesis of nucleotide sugars
  • basic FUNCTION
  • catalyzing the reaction which converts mannose-1-phosphate and GTP to GDP-mannose which is involved in the production of N-linked oligosaccharides
  • may be involved in the regulation of cell cycle progression
  • catalyzes the formation of GDP-mannose from mannose-1-phosphate and GTP, and is required in four glycosylation pathways
  • CELLULAR PROCESS cell cycle, progression
