Protein Information (annotations from UniProt)

Database IDHIV0002179
UniProt IDQ3MUY2
Primary gene name(s)PIGY
Synonym gene name(s)unknown
Protein namePhosphatidylinositol N-acetylglucosaminyltransferase subunit Y
Protein functionComponent of the GPI-GlcNAc transferase, GPI-GnT complex in the endoplasmic reticulum, a complex that catalyzes transfer of GlcNAc from UDP-GlcNAc to an acceptor phosphatidylinositol, the first step in the production of GPI-anchors for cell surface proteins. May act by regulating the catalytic subunit PIGA. {ECO:0000269|PubMed:16162815}.
Subcellular locationEndoplasmic reticulum membrane {ECO:0000269|PubMed:16162815};
Multi-pass membrane protein {ECO:0000269|PubMed:16162815}.
