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]. * **UniProt Summary**: Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the first alpha-1,4-linked mannose of the glycosylphosphatidylinositol precursor of GPI-anchor (By similarity). May act as suppressor of replication stress and chromosome missegregation. {ECO:0000250, ECO:0000269|PubMed:23446422}. |PigN| |Phosphodiest| |Sulfatase| |mannose-ethanolamine phosphotransferase activity| |preassembly of GPI anchor in ER membrane| |GPI anchor biosynthetic process| |GPI anchor metabolic process| |glycolipid biosynthetic process| |protein lipidation| |lipoprotein biosynthetic process| |glycolipid metabolic process| |phosphatidylinositol biosynthetic process| |liposaccharide metabolic process| |lipoprotein metabolic process| |membrane lipid biosynthetic process| |phosphatidylinositol metabolic process| |membrane lipid metabolic process| |glycerophospholipid biosynthetic process| |glycerolipid biosynthetic process| |phospholipid biosynthetic process| |glycerophospholipid metabolic process| |phospholipid metabolic process| |glycerolipid metabolic process| |organophosphate biosynthetic process| |lipid biosynthetic process| |carbohydrate derivative biosynthetic process| |organophosphate metabolic process| |endoplasmic reticulum membrane| |cellular lipid metabolic process| |carbohydrate derivative metabolic process| |lipid metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp443|SNS-032 15μM R08 exp443]]|1.73| No correlation found to any other genes in chemogenomics.
