id: GO:0000506
name: glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex
namespace: cellular_component
type: go
obsolete: False

Description: An enzyme complex that catalyzes the transfer of GlcNAc from UDP-GlcNAc to an acceptor phosphatidylinositol, the first step in the production of GPI anchors for cell surface proteins. The complex contains PIG-A, PIG-C, PIG-H, PIG-Q, PIG-P, and DPM2 in human, and Eri1p, Gpi1p, Gpi2p, Gpi15p, Gpi19p, and Spt14p in budding yeast.
