Function

edit

Phosphomannomutase 2 catalyzes the isomerization of mannose 6-phosphate to mannose 1-phosphate. Mannose 1-phosphate is a precursor to GDP-mannose necessary for the synthesis of dolichol-P-oligosaccharides. Mutations in the gene have been shown to cause defects in the protein glycosylation pathway which manifest as the congenital disorder of glycosylation PMM2 deficiency.[5]
