Summaries for PIGW Gene

Entrez Gene Summary for PIGW Gene

  • The protein encoded by this gene is an inositol acyltransferase that acylates the inositol ring of phosphatidylinositol. This occurs in the endoplasmic reticulum and is a step in the biosynthesis of glycosylphosphatidylinositol (GPI), which anchors many cell surface proteins to the membrane. Defects in this gene are a cause of West syndrome and hyperphosphatasia with mental retardation syndrome. [provided by RefSeq, Oct 2016]

GeneCards Summary for PIGW Gene

PIGW (Phosphatidylinositol Glycan Anchor Biosynthesis Class W) is a Protein Coding gene. Diseases associated with PIGW include Hyperphosphatasia With Mental Retardation Syndrome 5 and Hyperphosphatasia-Intellectual Disability Syndrome. Among its related pathways are Glycosylphosphatidylinositol (GPI)-anchor biosynthesis and Metabolism of proteins. GO annotations related to this gene include transferase activity, transferring acyl groups.

UniProtKB/Swiss-Prot for PIGW Gene

  • Required for the transport of GPI-anchored proteins to the plasma membrane (PubMed:24367057). Probable acetyltransferase, which acetylates the inositol ring of phosphatidylinositol during biosynthesis of GPI-anchor. Acetylation during GPI-anchor biosynthesis is not essential for the subsequent mannosylation and is usually removed soon after the attachment of GPIs to proteins (By similarity).
