Pigyl - phosphatidylinositol glycan anchor biosynthesis, class Y-like

This gene encodes a homolog of a human protein that functions in glycosylphosphatidylinositol biosynthesis. The human protein is expressed from an unusual locus that encodes two distinct proteins in upstream and downstream CDSes; however, in mouse these two proteins are expressed from distinct loci. The product of this locus is highly similar to the protein expressed from the human downstream CDS. A separate mouse locus on chromosome 6 is orthologous to the human locus and encodes a protein similar to the human protein expressed from the upstream CDS. [provided by RefSeq, Jul 2008]
