Predicted to be involved in GPI anchor biosynthetic process and positive regulation of metabolic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be part of glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex. Orthologous to several human genes including PIGY (phosphatidylinositol glycan anchor biosynthesis class Y). [provided by Alliance of Genome Resources, Apr 2022]
