PIG-Y Rabbit Polyclonal Antibody

The protein encoded by this gene is part of the GPI-N-acetylglucosaminyltransferase (GIP-GnT) complex which initiates the biosynthesis of glycosylphosphatidylinositol (GPI) . GPI is synthesized in the endoplasmic reticulum and serves as an anchor for many surface proteins. Proteins containing GPI anchors can have an important role in cell-cell interactions. The transcript for this gene is bicistronic. The downstream open reading frame encodes this GPI-GnT complex protein, while the upstream open reading frame encodes a protein with unknown function, as represented by GeneID:100996939. [provided by RefSeq, Aug 2012], function:Component of the GPI-GlcNAc transferase (GPI-GnT) complex in the endoplasmic reticulum, a complex that catalyzes transfer of GlcNAc from UDP-GlcNAc to an acceptor phosphatidylinositol, the first step in the production of GPI-anchors for cell surface proteins. May act by regulating the catalytic subunit PIGA., miscellaneous:PIGY is derived from the same bicistronic transcript that encodes this protein., miscellaneous:PREY is derived from the same bicistronic transcript that encodes this protein., pathway:Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis., similarity:Belongs to the PREY family., similarity:Contains 1 TRM112 domain., subunit:Interacts with the GPI-GnT complex composed of PIGA, PIGC, PIGH, PIGP, PIGQ and DPM2. Interacts directly with PIGA. Does not interact with Ras proteins.
