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.

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

Associates with PIGA, PIGC, PIGH, PIGP and DPM2. The latter is not essential for activity.

Subcellular location

Membrane; Multi-pass membrane protein Potential.

Sequence similarities

Belongs to the PIGQ family.
