Entrez ID 85365
Gene name ALG2 alpha-1,3/1,6-mannosyltransferase
Gene symbol ALG2
Synonyms (NCBI Gene)
CDG1ICDGIiCMS14CMSTA3NET38hALPG2
Chromosome 9
Chromosome location 9q22.33
Summary This gene encodes a member of the glycosyltransferase 1 family. The encoded protein acts as an alpha 1,3 mannosyltransferase, mannosylating Man(2)GlcNAc(2)-dolichol diphosphate and Man(1)GlcNAc(2)-dolichol diphosphate to form Man(3)GlcNAc(2)-dolichol diph
