General annotation (Comments)

Function	Part of the complex catalyzing the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol, the first step of GPI biosynthesis. Ref.3
Catalytic activity	UDP-N-acetyl-D-glucosamine + 1-phosphatidyl-1D-myo-inositol = UDP + 6-(N-acetyl-alpha-D-glucosaminyl)-1-phosphatidyl-1D-myo-inositol.
Pathway	Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis.
Subunit structure	Component of a complex with GPI1, GPI2, GPI3, GPI15 and ERI1 Probable.
Subcellular location	Membrane; Multi-pass membrane protein Potential.
Sequence similarities	Belongs to the PIGH family.
Sequence caution	The sequence AAT93131.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAA95905.1 differs from that shown. Reason: Erroneous gene model prediction.
