UniProtKB description: Component of the GPI transamidase complex, necessary for transfer of GPI to proteins (PubMed:34576938). Mediates GPI anchoring in the endoplasmic reticulum, by replacing a protein's C-terminal GPI attachment signal peptide with a pre-assembled GPI. During this transamidation reaction, the GPI transamidase forms a carbonyl intermediate with the substrate protein.
