Description:
ERF is a member of the ETS family of transcription factors that play key roles in the regulation of cell proliferation and differentiation. Members of this family share a highly conserved DNA-binding domain, the ETS domain, that recognizes the core consensus DNA sequence GGAA/T of target genes. ERF functions as a transcriptional repressor that binds to the H1 element of the ETS2 promoter. ETS2 is a transcription factor activating transcription. Functional studies showed that epigenetic silencing of ERF associates with elevated haemoglobin F (HbF) in β0-thalassaemia-affected individuals via DNA methyltransferase 3A (DNMT3A)-mediated hypermethylation of the ERF promoter. The depletion of ERF activates HbF in primary CD34+ HSPCs and HUDEP-2 cells; findings were validated in vivo with engraftment of edited human CD34+ HSPCs into immunodeficient mice. ERF acts as a transcriptional repressor of γ-globin genes through direct binding on their distant regulatory elements; 3.6 kb upstream of HBG2 and 1.5 kb downstream of HBG1. These regions are accessible for several known transcription factors and histone modification markers. Epigenetic inactivation of ERF reactivates γ-globin expression in β-thalassaemia without altering the terminal erythroid differentiation. ERF acts as a potential regulator of HbF expression and a candidate therapeutic option for patients with beta-haemoglobinopathies.
