Previous GeneCards Identifiers for PIGT Gene
This gene encodes a protein 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 an essential component of the multisubunit enzyme, GPI transamidase. GPI transamidase mediates GPI anchoring in the endoplasmic reticulum, by catalyzing the transfer of fully assembled GPI units to proteins. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]
GeneCards Summary for PIGT Gene
PIGT (Phosphatidylinositol Glycan Anchor Biosynthesis, Class T) is a Protein Coding gene. Diseases associated with PIGT include paroxysmal nocturnal hemoglobinuria 2 and multiple congenital anomalies-hypotonia-seizures syndrome 3. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include GPI-anchor transamidase activity.
UniProtKB/Swiss-Prot for PIGT Gene
Component of the GPI transamidase complex. Essential for transfer of GPI to proteins, particularly for formation of carbonyl intermediates.
