.... By DNAse I footprinting and gel mobility shift assays, we identified several GATA-1 and one AP-1/NF-E2-binding sites located inside these regions. These results strengthen the idea that, like for all other globin genes, flanking regions contribute in vivo to the regulation of human α-globin gene expression...

... GATA-1 in erythrocyte and megakaryocyte differentiation. GATA-1 has two zinc fingers essential for normal function. The C-terminal finger is necessary for DNA binding. The N-terminal finger mediates interaction with FOG-1, a cofactor for GATA-1. Mutations in the N-terminal zinc finger of GATA-1 result...

...Kinuko Ohneda; Masayuki Yamamoto The transcription factors GATA-1 and GATA-2 play key roles in gene regulation during erythropoiesis. Gene ablation studies in mouse revealed that GATA-2 is crucial for the maintenance and proliferation of immature hematopoietic progenitors, whereas GATA-1...
