This study demonstrates that the transcription factor GATA-2 is required in the ectoderm for normal blood development. Loss of GATA-2 function produces hematopoietic defects similar to those caused by disruption of BMP signaling or CaMKIV activity. The data support a linear pathway in which BMPs induce GATA-2 transcription, while CaMKIV negatively regulates GATA-2 activity post-translationally, revealing a coordinated mechanism controlling early blood lineage specification.}, url = {http://digitalcollections.ohsu.edu/record/2155}, doi = {https://doi.org/10.6083/M4CJ8BQB}, }
