PIGK (human)

Overview
PIGK 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. Belongs to the peptidase C13 family. Note: This description may include information from UniProtKB.
