LYN and activated (phosphorylated) SYK phosphorylate BTK (Baba et al. 2001, Lin et al. 2009, also inferred from chicken homologs and mouse homologs) after BTK is recruited to the plasma membrane by phosphorylated BLNK (Baba et al. 2001) and phosphoinositol 3,4,5-trisphosphate (PIP3) (Salim et al. 1996). Phosphorylation of tyrosine-551 occurs within 30 seconds of B cell receptor activation and returns to low phosphorylation after 30 minutes (Nisitani et al. 1999).
