Pyurf - Pigy upstream reading frame Gene

This gene encodes a small protein with a conserved DUF343 domain. The human ortholog of this gene expresses two distinct proteins from upstream and downstream coding regions. The upstream CDS encoding a DUF343 domain-containing protein has been conserved at this mouse locus, but the downstream CDS encoding a subunit of an enzyme involved in glycosylphosphatidylinositol biosynthesis has not been conserved. Instead, a separate locus on mouse chromosome 9 encodes the mouse homolog of the human phosphatidylinositol glycan anchor biosynthesis, class Y protein. [provided by RefSeq, Jul 2008]
