Comment typeDescription
Catalytic ActivityUDP-N-acetyl-D-glucosamine + 1-phosphatidyl- 1D-myo-inositol = UDP + 6-(N-acetyl-alpha-D-glucosaminyl)-1- phosphatidyl-1D-myo-inositol.
FunctionPart of the complex catalyzing the transfer of N- acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis.
PathwayGlycolipid biosynthesis; glycosylphosphatidylinositol- anchor biosynthesis.
SimilarityBelongs to the PIGH family.
Subcellular LocationCytoplasm.
SubunitAssociates with PIGA, PIGC, PIGP, PIGQ and DPM2. The latter is not essential for activity.
