The methyl-CpG binding transcriptional repressor MeCP2 stably associates with nucleosomal DNA.

Chandler SP , Guschin D , Landsberger N , Wolffe AP .

We have investigated the interactions of the methyl-CpG binding transcriptional repressor MeCP2 with nucleosomal DNA. We find that MeCP2 forms discrete complexes with nucleosomal DNA associating with methyl-CpGs exposed in the major groove via the methyl-CpG-binding domain (MBD). In addition to the MBD, the carboxyl-terminal segment of MeCP2 facilitates binding both to naked DNA and to the nucleosome core. These observations provide a molecular mechanism by which MeCP2 can gain access to chromatin in order to target corepressor complexes that further modify chromatin structure.
