GGDB:

ALG2 encodes alpha-mannosyltransferase that is involved in the synthesis of lipid-linked oligosaccharides in the endoplasmic reticulum. GDP-mannose is used for the donor substrate. ALG2 appears to be involved in transfer of both alpha-1,3- and alpha-1,6-linked mannose. ALG2 complements the defect of the yeast alg2 mutant. Mutation of ALG2 is associated with congenital disorder of glycosylation type 1I.
