GPI-anchor transamidase is an enzyme that in humans is encoded by the PIGK gene.This gene encodes a member of the cysteine protease family C13 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 a member of the multisubunit enzyme GPI transamidase and is thought to be its enzymatic component.
