GDP-Mannose Pyrophosphorylase B; GTP-Mannose-1-Phosphate Guanylyltransferase Beta; Mannose-1-Phosphate Guanyltransferase Beta; EC 2.7.7.13; MDDGA14; MDDGB14; MDDGC14

This gene is thought to encode a GDP-mannose pyrophosphorylase. The encoded protein catalyzes the conversion of mannose-1-phosphate and GTP to GDP-mannose, a reaction involved in the production of N-linked oligosaccharides. Alternatively spliced transcript variants encoding distinct isoforms have been described.
