PIGQ
Phosphatidylinositol N-acetylglucosaminyltransferase subunit Q is an enzyme that in humans is encoded by the PIGQ gene.
This gene is involved in the first step in glycosylphosphatidylinositol -anchor biosynthesis. The GPI-anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This gene encodes a N-acetylglucosaminyl transferase component that is part of the complex that catalyzes transfer of N-acetylglucosamine from UDP-GlcNAc to phosphatidylinositol.Interactions
PIGQ has been shown to interact with PIGH, PIGA and PIGC.
