Kinase-active JAK2 leads to the phosphorylation of STAT3 on Y705. 2 / 2
2 |

"Maximal activation of STAT3 requires phosphorylation at both Tyr705 and Ser727 sites (14). Although JAK2 kinase is shown to be responsible for phosphorylating STAT3 at Tyr705, we have shown that IL-1 receptor associated kinase 1 (IRAK-1) is capable of selectively phosphorylating STAT3 at Ser727 (15)."

"Induction of STAT3 Tyr705 and Ser727 phosphorylations by Galpha(s)QL was suppressed by inhibition of protein kinase A, Janus kinase 2/3, Rac1, c-Jun N-terminal kinase (JNK), or phosphatidylinositol 3-kinase, and a similar profile was observed in response to beta2-adrenergic receptor stimulation"
