该基因编码一种参与糖基磷脂酰肌醇（gpi）锚定生物合成的蛋白质。GPI锚定物是一种糖脂，在其核心骨架中含有三个甘露糖分子，在许多血细胞中被发现，用来将蛋白质锚定在细胞表面编码蛋白和另一个gpi合成蛋白pigo在gpi中的乙醇胺磷酸转移到第三个甘露糖中起作用。另外，还描述了编码不同亚型的剪接转录变体[由RefSeq提供，2008年7月]
This gene encodes a protein involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI-anchor, a glycolipid containing three mannose molecules in its core backbone, is found on many blood cells where it serves to anchor proteins to the cell surface. The encoded protein and another GPI synthesis protein, PIGO, function in the transfer of ethanolaminephosphate to the third mannose in GPI. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
