Webb9 mars 2024 · The phosphorylation of phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] forms phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P3] via growth factor receptors and G protein-coupled receptors. This phospholipid acts as a second messenger for the recruitment of cytoplasmic proteins to a specific plasma membrane or intimal position.
