Previous GeneCards Identifiers for PIGB Gene
This gene encodes a transmembrane protein that is located in the endoplasmic reticulum and is involved in GPI-anchor biosynthesis. The glycosylphosphatidylinositol (GPI) anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This gene is thought to encode a member of a family of dolichol-phosphate-mannose (Dol-P-Man) dependent mannosyltransferases. [provided by RefSeq, Jul 2008]
GeneCards Summary for PIGB Gene
PIGB (Phosphatidylinositol Glycan Anchor Biosynthesis Class B) is a Protein Coding gene. Diseases associated with PIGB include Epileptic Encephalopathy, Early Infantile, 80 and Griscelli Syndrome. Among its related pathways are Metabolism of proteins and Glycosylphosphatidylinositol (GPI)-anchor biosynthesis. Gene Ontology (GO) annotations related to this gene include transferase activity, transferring glycosyl groups and mannosyltransferase activity. An important paralog of this gene is ALG9.
