This gene encodes a protein that is involved in GPI-anchor
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. [provided by
