Reaction: CD19 is phosphorylated

- in pathway: Antigen activates B Cell Receptor (BCR) leading to generation of second messengers
In response to BCR activation, CD19 in a stable complex with VAV1 is phosphorylated by Src kinases (Chalupny et al. 1993, inferred from mouse homologs in Xu et al. 2002), one of which may be LYN (inferred from mouse homologs).
