The phosphatidylinositols (PtdIns) phosphates represent a small precentage of total membrane phospholipids. However, they play a critical role in the generation and transmission of cellular signals.1,2 PtdIns-(4,5)-P2 can be phosphorylated by phosphatidylinositol (PI)-3-kinase to make PtdIns-(3,4,5)-P3, which initiates an intricate signaling cascade that has been implicated in cancer.3 PtdIns-(3,4,5)-P3 fluorescein is a fluorescent probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.
