Tyrosine-protein kinase JAK2

JAK2 belongs to Tyr protein kinase family. JAK2 is shown to phosphorylate histone H3 at tyrosine 41 position which has an inhibitory effect on the binding of HP1-alpha leading to loss of repression. Knockdown of JAK2 is shown to repress Imo2 oncogene by increased binding of HP-1 on its promoter in human leukaemia cells providing hints for the process of leukemogenesis. (PMID: 19783980).
