Phosphorylated BLNK (also called BASH or SLP-65) at the plasma membrane recruits BTK, PLC gamma, VAV, GRB2, and NCK (Fu and Chan 1997, Fu et al. 1998, Wienands et al. 1998, Su et al. 1999, Baba et al. 2001, Chiu et al. 2002). The SH2 domain of BTK binds phosphorylated BLNK (Hashimoto et al. 1999, Su et al. 1999, Baba et al. 2001). BLNK is constitutively bound to CIN85 and phosphorylated BLNK is bound to a large complex containing CIN85, SOS1, GRB2, phosphorylated SYK, and the B cell receptor.
