Research Abstract |
GATA1 is a transcription factor essential for erythroid/megakaryocytic cell differentiation. We found that three elements within promoter-proximal enhancer differentially contribute to spatio-temporal expression of the Gata1 gene in vivo. In addition, we found that loss of the GATA1-FOG1 interaction causes a unique combination of membrane protein deficiency, leading to the hemolysis. We also found that GATA1 has two independent transactivation domains, N-TAD and C-TAD, and both retain redundant as well as specific activities for proper hematopoiesis in vivo.
