The discovery of JAK2V617F as an acquired mutation in the majority of patients with myeloproliferative disorders (MPDs) and the key role of the JAK2-STAT5 signaling cascade in normal hematopoiesis has focused attention on the downstream transcriptional targets of STAT5. Despite evidence of its vital role in normal erythropoiesis and its ability to recapitulate many of the features of myeloid malignancies, including the MPDs, few functionally validated targets of STAT5 have been described. Here we used a combination of comparative genomics and chromatin immunoprecipitation assays to identify ID1 as a novel target of the JAK2-STAT5 signaling axis in erythroid cells. STAT5 binds and transactiva..
