glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex

Term ID

GO:0000506

Synonyms

• GPI-GlcNAc transferase complex
• GPI-GnT complex
• GPI-N-acetylglucosaminyltransferase complex

Definition

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. (2)
