Protein-coding gene in the species Homo sapiens
GPI transamidase component PIG-S is an enzyme that in humans is encoded by the PIGS gene .[ 5] biosynthesis .
The glycosylphosphatidylinositol (GPI) anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This gene encodes an essential component of the multisubunit enzyme, GPI transamidase . GPI transamidase mediates GPI anchoring in the endoplasmic reticulum , by catalyzing the transfer of fully assembled GPI units to proteins.[ 5]
