Background
The JH2 domain of Jak2 has been shown to autophosphorylate two negative regulatory sites on Jak2, Ser523 and Tyr570. In the absence of cytokine stimulation, Jak2 is constitutively phosphorylated on Ser523, effectively inhibiting its activity (6,7). Mutation in the JH2 domain can lead to an increase in Jak2 activity, resulting in myeloproliferative neoplasms (MPNs) (8).
