Previous GeneCards Identifiers for PIGK Gene
This gene encodes a member of the cysteine protease family C13 that is involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI-anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This protein is a member of the multisubunit enzyme, GPI transamidase and is thought to be its enzymatic component. GPI transamidase mediates GPI anchoring in the endoplasmic reticulum, by catalyzing the transfer of fully assembled GPI units to proteins. [provided by RefSeq, Jul 2008]
GeneCards Summary for PIGK Gene
PIGK (Phosphatidylinositol Glycan Anchor Biosynthesis Class K) is a Protein Coding gene. Among its related pathways are Metabolism and Transport to the Golgi and subsequent modification. GO annotations related to this gene include cysteine-type endopeptidase activity and GPI anchor binding. An important paralog of this gene is LGMN.
UniProtKB/Swiss-Prot for PIGK Gene
Mediates GPI anchoring in the endoplasmic reticulum, by replacing a proteins 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.
