Active FLT3 is bound by the E3 ubiquitin protein ligase CBL. In addition to direct interaction with the FLT3 receptor, CBL may also interact indirectly through GRB2. CBL interacts with the receptor in a FL ligand-dependent way, and mutation of FLT3 tyrosine residues Y589 and Y599 abrogates FLT3-dependent CBL phosphorylation (Sargin et al, 2007; Reindl et al, 2009; Heiss et al, 2006). FLT3-mediated phosphorylation of CBL promotes receptor ubiquitination and internalization, consistent with what is observed with other Type III receptor tyrosine kinases (reviewed in Kazi and Ronnstrand, 2019).
