GPI-GlcNAc transferase complex, PIG-H component, conserved domain (IPR019328)

Short name: GPI-GlcNAc_Trfase_PIG-H_dom

Overlapping homologous superfamilies


Family relationships



This entry represents a conserved domain found in PIG-H proteins. PIG-H is a family of conserved proteins that complexes with three other proteins to form the GPI-GnT (glycosylphosphatidylinositol anchor biosynthesis transferase) complex. It appears to be a peripheral membrane protein that faces the cytoplasm and which is involved in the first step in GPI anchor formation.
