Term:glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex
go back to main search page
Accession:GO:0000506 term browser browse the term
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.
Comment:Note that this term should not be confused with 'GPI-anchor transamidase complex ; GO:0042765', which represents a distinct complex with a different catalytic activity.
Synonyms:exact_synonym: GPI-GlcNAc transferase complex;   GPI-GnT complex;   GPI-N-acetylglucosaminyltransferase complex
