PIGW( Human )
phosphatidylinositol glycan anchor biosynthesis class W
Alias
Gwt1|HPMRS5
The protein encoded by this gene is an inositol acyltransferase that acylates the inositol ring of phosphatidylinositol. This occurs in the endoplasmic reticulum and is a step in the biosynthesis of glycosylphosphatidylinositol (GPI), which anchors many cell surface proteins to the membrane. Defects in this gene are a cause of West syndrome and hyperphosphatasia with mental retardation syndrome. [provided by RefSeq, Oct 2016].
