Phosphatidylinositol 4,5-bisphosphate 3-kinase (PI3K) associated with EPOR phosphorylates phosphatidylinositol 4,5-bisphosphate to yield phosphatidyl 3,4,5-trisphosphate (Kubota et al. 2001, Schmidt et al. 2004). PI3K binds the phosphorylated EPOR directly or indirectly via phosphorylated IRS2 or phosphorylated GAB1 (Bouscary et al. 2003).
