General Information

Term

GPI-anchor transamidase complex

ID (Ontology)

GO:0042765 (Gene Ontology)

Definition

An enzyme complex which in humans and yeast consists of at least five proteins; for example, the complex contains GAA1, GPI8, PIG-S, PIG-U, and PIG-T in human, and Gaa1p, Gab1p, Gpi8p, Gpi16p, and Gpi17p in yeast. Catalyzes the posttranslational attachment of the carboxy-terminus of a precursor protein to a GPI-anchor.[ PubMed:12802054 ]

Also Known As

"GPIT complex"
