WebERYTHROPOIESIS GATA1 is considered the “master” transcription factor of erythropoiesis as it transcriptionally regulates all aspects of erythroid maturation and function.9 The GATA1 protein has three main functional domains: An N-terminal trans-activation domain (N-TAD) and two homologous ZnF WebOct 30, 2024 · A luciferase reporter assay revealed that this SNP impairs GATA1-mediated trans-regulation of ARHGEF12, and quantitative polymerase chain reaction studies confirmed that the homozygotes status is associated with an approximately 61% reduction in ARHGEF12 expression (P=0.0088). Consequently, erythropoiesis was affected at the …

WebAs for GATA1, the first evidence for an essential role in erythropoiesis came from the observation that KLF1 knockout mice die in utero around E15 due to fatal anemia (Nuez et al., 1995; Perkins et al., 1995). Given that KLF1 is an important activator of β-globin, lethality was first attributed to β-thalassemia.
