β-hemoglobinopathies affect millions of people around the world. Research into treatments for these conditions has focused on methods to increase γ-globin expression, because increased levels of γ-globin ameliorate or reduce the severity of symptoms. As more and more studies have been done, a few proteins have emerged as having crucial roles in γ-globin repression and have been established as key genes to study. These are Krüppel-like factor 1 (KLF1), B cell CLL/lymphoma 11A (BCL11A), and methyl binding domain 2 (MBD2). The roles of these proteins in the switch from fetal to adult hemoglobin and in repressing γ-globin expression have been …

The MBD2-NuRD co-repressor complex is an epigenetic regulator of the developmental silencing of embryonic and fetal β-type globin genes in adult erythroid cells as well as aberrant methylation-dependent silencing of tumor suppressor genes in neoplastic diseases. Biochemical characterization of the MBD2-NuRD complex in chicken erythroid cells identified RbAp46/48, HDAC1/2, MTA1/2/3, p66α/β, Mi2α/β and MBD2 to comprise this multi-protein complex.
In the work presented in Chapter 2, we have pursued biophysical and molecular studies to describe a previously uncharacterized domain of human MBD2 (MBD2IDR). Biophysical analyses show that MBD2IDR is an intrinsically disordered region (IDR). Despite this inherent …
