GATA zinc finger domain‐containing protein 2A ( <i>GATAD2A</i> ) deficiency reactivates fetal haemoglobin in patients with β‐thalassaemia through impaired formation of methyl‐binding domain protein 2 (MBD2)‐containing nucleosome remodelling and deacetylation (NuRD) complex

چکیده

Reactivation of fetal haemoglobin (HbF) expression is an effective way to treat β-thalassaemia and sickle cell anaemia. In the present study, we identified a novel GATA zinc finger domain-containing protein 2A (GATAD2A) mutation, which contributed elevation HbF ameliorated clinical severity in patient with β-thalassaemia, by targeted next-generation sequencing. Knockout GATAD2A led significant induction both human umbilical cord blood-derived erythroid progenitor-2 (HUDEP-2) cluster differentiation (CD)34+ cells detectable impact on differentiation. Furthermore, heterozygous knockout impaired recruitment chromodomain helicase DNA-binding 4 (CHD4) methyl-binding domain 2 (MBD2)-containing nucleosome remodelling deacetylation (NuRD) complex. Our data suggest that mutations causing haploinsufficiency might contribute amelioration patients β-thalassaemia.

Sall4 controls differentiation of pluripotent cells independently of the Nucleosome Remodelling and Deacetylation (NuRD) complex

Sall4 is an essential transcription factor for early mammalian development and is frequently overexpressed in cancer. Although it is reported to play an important role in embryonic stem cell (ESC) self-renewal, whether it is an essential pluripotency factor has been disputed. Here, we show that Sall4 is dispensable for mouse ESC pluripotency. Sall4 is an enhancer-binding protein that prevents p...

The NuRD nucleosome remodelling complex and NHK-1 kinase are required for chromosome condensation in oocytes

Chromosome condensation during cell division is one of the most dramatic events in the cell cycle. Condensin and topoisomerase II are the most studied factors in chromosome condensation. However, their inactivation leads to only mild defects and little is known about the roles of other factors. Here, we took advantage of Drosophilaoocytes to elucidate the roles of potential condensation factors...

The multi-zinc finger protein ZNF217 contacts DNA through a two-finger domain.

Classical C2H2 zinc finger proteins are among the most abundant transcription factors found in eukaryotes, and the mechanisms through which they recognize their target genes have been extensively investigated. In general, a tandem array of three fingers separated by characteristic TGERP links is required for sequence-specific DNA recognition. Nevertheless, a significant number of zinc finger pr...

Protein Phosphatase 2A Reactivates FOXO3a through a Dynamic Interplay with 14-3-3 and AKT

Forkhead box transcription factor FOXO3a, a key regulator of cell survival, is regulated by reversible phosphorylation and subcellular localization. Although the kinases regulating FOXO3a activity have been characterized, the role of protein phosphatases (PP) in the control of FOXO3a subcellular localization and function is unknown. In this study, we detected a robust interaction between FOXO3a...
