Phosphorylated JAK2 in a complex with EPOR and GAB1 phosphorylates GAB1 on unknown tyrosine residues (Lecoq-Lafon et al. 1999, Wickrema et al. 1999, Bouscary et al. 2003, Fukumoto et al. 2009). Phosphorylated GAB1 serves as a scaffold for binding downstream signaling molecules including phosphatidylinositol 4,5-bisphosphate 3-kinase (PI3K) (Bouscary et al. 2003).
