After phosphorylation on tyrosine-551 by LYN or SYK, BTK autophosphorylates tyrosine-223 (Wahl et al. 1997, Nore et al. 2003, and inferred from mouse homologs). Maximum autophosphorylation occurs 5 minutes after activation of the B cell receptor and returns to low phosphorylation after 30 minutes (Nisitani et al. 1999).
