Summary
Predicted to enable phosphatidylinositol N-acetylglucosaminyltransferase activity. Involved in GPI anchor biosynthetic process. Located in endoplasmic reticulum. Part of glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex. Human ortholog(s) of this gene implicated in glycosylphosphatidylinositol biosynthesis defect 16. Orthologous to human PIGC (phosphatidylinositol glycan anchor biosynthesis class C). [provided by Alliance of Genome Resources, Oct 2024]
