GENE INFORMATION
Gene name	PIGK (HGNC Symbol)
Synonyms	GPI8, hGPI8
Description	Phosphatidylinositol glycan anchor biosynthesis, class K (HGNC Symbol)
Entrez gene summary	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. GPI transamidase mediates GPI anchoring in the endoplasmic reticulum, by catalyzing the transfer of fully assembled GPI units to proteins. [provided by RefSeq, Jul 2008]
