This gene encodes a protein that is involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI-anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This protein is expressed in the endoplasmic reticulum and transfers phosphoethanolamine (EtNP) to the first mannose of the GPI anchor. Two alternatively spliced variants, which encode an identical isoform, have been reported. [provided by RefSeq, Jul 2008]
PIGN (Phosphatidylinositol Glycan Anchor Biosynthesis Class N) is a Protein Coding gene. Diseases associated with PIGN include Multiple Congenital Anomalies-Hypotonia-Seizures Syndrome 1 and Fryns Syndrome. Among its related pathways are Metabolism of proteins and Metabolism. Gene Ontology (GO) annotations related to this gene include transferase activity and sulfuric ester hydrolase activity.
