Ghosh et al. report findings showing that the atypical kinase RIOK2 functions as a winged helix-turn-helix domain containing transcription factor that regulates the differentiation of human hematopoietic stem and progenitor cells toward erythroid, myeloid and megakaryocytic lineages. RIOK2 enhances GATA1 and KLF1 expression, while suppressing other transcription factors like RUNX3, SPI1 and GATA2.
