WebDec 4, 2024 · Telomere length is maintained by either telomerase, a reverse transcriptase, or alternative lengthening of telomeres (ALT), a mechanism that utilizes homologous recombination (HR) proteins. Since access to DNA for HR enzymes is regulated by the chromatin status, it is expected that telomere elongation is linked to epigenetic … WebAug 22, 2003 · Human MeCP2 Is a Unique Architectural Chromatin-binding Protein—The experiments in this study were designed to determine whether interaction of MeCP2 with …
WebJun 12, 2016 · MECP2 is a transcriptional repressor, although when it forms complexes with the appropriate molecules, it can become a transcriptional activator. For all of these aspects, Rett syndrome, which is caused by MECP2 mutations, is considered a paradigmatic example of a ‘chromatin disorder’. WebAs MeCP2 expression is nearly equivalent to that of core histones and because it binds DNA throughout the genome, one possible function of MeCP2 is to regulate the 3D-structure of chromatin. Here, to examine whether and how MeCP2 levels impact chromatin structure, we used high-resolution confocal and electron microscopy and examined ...

WebMeCP2, encoded by the MECP2 gene in humans and the Mecp2 gene in rodents, was first characterized as a methyl CpG DNA binding protein in 1992, thereby establishing it as an epigenetic reader of DNA methylation ( Meehan et al., 1992 ).
WebIntroduction. Epigenetics is the study of heritable changes in the gene function without any change in the DNA sequence. Epigenetics includes DNA methylation, histone modification, chromatin remodeling, and noncoding RNAs (ncRNAs).
