GRB10 promotes signaling through the AKT pathway downstream of active FLT3. GRB10 is recruited to the active receptor by binding to phosphorylated tyrosine residues 572 and 793. Once bound, GRB10 recruits PI3K by direct interaction with the p85 regulatory subunit and subsequent recruitment of catalytic subunit (Kazi and Ronnstrand, 2013; reviewed in Kazi and Ronnstrand, 2019).
