PIGF编码参与糖基磷脂酰肌醇(GPI)-锚定生物合成的蛋白质。GPI锚是一种在其核心骨架中含有三个甘露糖分子的糖脂,它存在于许多血细胞上,用于将蛋白质锚定在细胞表面。编码的蛋白质和另一种GPI合成蛋白PIGO在乙醇胺磷酸盐转移至GPI中的第三甘露糖中起作用。其相关途径包括VEGF信号通路和蛋白质代谢。与PIGF相关的疾病包括具有小头畸形和特征性面部的短身材和先兆子痫。
Glycosylphosphatidylinositol (GPI) anchors attach certain proteins to the cell surface membrane. Proteins with appropriate C-terminal signal peptides are transferred to the preformed glycolipid anchor in the endoplasmic reticulum and transported to the cell surface as a single unit. PIGF encodes 1 of the enzymes involved in GPI biosynthesis.
