Oxidative damage to methyl-CpG sequences inhibits the binding of the methyl-CpG binding domain (MBD) of methyl-CpG binding protein 2 (MeCP2).

Cytosine methylation in CpG dinucleotides is believed to be important in gene regulation, and is generally associated with reduced levels of transcription. Methylation-mediated gene silencing involves a series of DNA-protein and protein-protein interactions that begins with the binding of methyl-CpG binding proteins (MBPs) followed by the recruitment of histone-modifying enzymes that together p...

Methyl CpG binding protein 2 (MeCP2) enhances photodimer formation at methyl-CpG sites but suppresses dimer deamination

Spontaneous deamination of cytosine to uracil in DNA is a ubiquitous source of C→T mutations, but occurs with a half life of ∼50 000 years. In contrast, cytosine within sunlight induced cyclobutane dipyrimidine dimers (CPD's), deaminate within hours to days. Methylation of C increases the frequency of CPD formation at PyCG sites which correlate with C→T mutation hotspots in skin cancers. MeCP2 ...

Specific mutations in methyl-CpG-binding protein 2 confer different severity in Rett syndrome.

OBJECTIVE To determine if a relationship exists between the clinical features of Rett syndrome, an X-linked dominant neurodevelopmental disorder, and specific mutations in MECP2. METHOD Cross-sectional study of 245 girls and women with typical Rett syndrome seen between 1990 and 2004 in tertiary academic outpatient specialty clinics and who had complete MECP2 mutation analysis. A structured c...

Mechanism of transcriptional regulation by methyl-CpG binding protein MBD1.

MBD1 is a mammalian protein that binds symmetrically methylated CpG sequences and regulates gene expression in association with DNA methylation. This protein possesses a conserved sequence, named methyl-CpG binding domain (MBD), among a family of methyl-CpG binding proteins that mediate the biological consequences of the methylation. In addition, MBD1 has at least five isoforms due to alternati...

The methyl-CpG-binding protein MeCP2 and neurological disease.

The methyl-CpG-binding protein MeCP2 was discovered over 15 years ago as part of a search for proteins that selectively bind methylated DNA. It is a nuclear protein that is largely chromatin-bound and has a strong preference for binding to methylated DNA sequences in vivo. Evidence from model systems shows that MeCP2 can recruit the Sin3a co-repressor complex to promoters leading to transcripti...
