SH2B3 (also called LNK) is an adaptor protein that binds to tyrosine phosphorylated FLT3 through at least 3 tyrosine residues, Y572, Y591 and Y919 (Lin et al, 2012). SH3B2 is a known CBL interactor, so may contribute to FLT3 downregulation by promoting the CBL-dependent ubiquitination and internalization of the receptor, although this hasn't been formally demonstrated (Lv et al, 2017; Lin et al, 2012; reviewed in Kazi and Ronnstrand, 2019).
