PIG-H

PIG-H
PFAM accession number:PF10181
Interpro abstract (IPR019328):

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.

GO function:phosphatidylinositol N-acetylglucosaminyltransferase activity (GO:0017176)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry PIG-H
