Protein-coding gene in the species Homo sapiens
Phosphatidylinositol N-acetylglucosaminyltransferase subunit H is an enzyme that in humans is encoded by the PIGH gene.[5][6] The PIGH gene is located on the reverse strand of chromosome 14 in humans, and is neighbored by TMEM229B.[7]
This gene encodes an endoplasmic reticulum associated protein that is involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI anchor is a glycolipid found on many blood cells and which serves to anchor proteins to the cell surface. The protein encoded by this gene is a subunit of the GPI N-acetylglucosaminyl (GlcNAc) transferase that transfers GlcNAc to phosphatidylinositol (PI) on the cytoplasmic side of the endoplasmic reticulum.[6]
Interactions
PIGH has been shown to interact with PIGQ.[8]
