“…MeCP2 est à ce jour la protéine la mieux caractérisée pour se lier aux 5mC (ainsi qu'aux 5hmC et aux mCpH) [19]. La Figure 2 présente la structure et les principales caractéristiques des protéines liant l'ADN méthylé par l'intermédiaire d'un domaine MBD.…”

“…The recruitment of MeCP2, as a part of the methyl-binding protein family (MBDs), to methylated CpG dinucleotides represents a major mechanism by which DNA methylation can repress transcription [36,37]. MeCP2 has been shown to function as a repressor of transcription via its functional domains: a methyl-binding domain is necessary for its binding to 5-methylcytosine and a transcriptional repression domain that interacts with histone-modifying enzymes.…”

“…Another mechanism that may be involved in PR gene silencing in MDA-MB-231 cells is heterochromatinization at the PR CpG island. Several studies have suggested that dense DNA methylation promotes the binding of histone H1 or methyl-speci®c binding proteins that have a wide range of a nity and speci®city for methylated DNA (Levine et al, 1993;Lewis et al, 1992;Meehan et al, 1989;. These proteins may either compete with transcriptional activators for binding to a speci®c cis-acting site or help to stabilize a condensed chromatin structure that renders the DNA inaccessible to transcription factors (Kass et al, 1993).…”

“…Methylation of CpG islands has been shown to directly inhibit the binding of certain transcription factors to their recognition sites in vitro (Comb and Goodman, 1990;Iguchi-Ariga and Scha ner, 1989;Klempnauer, 1993;Prendergast and Zi , 1991). In addition, histone H1, as well as other proteins that may act as global transcriptional repressors by promoting heterochromatinization, preferentially bind to methylated DNA in vitro (Levine et al, 1993;Lewis et al, 1992;Meehan et al, 1989;. These results suggest that in vivo CpG island methylation can inhibit transcription factor binding to speci®c DNA sites and/or may cause a conformational change in chromatin that prevents transcription.…”
