+ | [https://www.uniprot.org/uniprot/MBD1_HUMAN MBD1_HUMAN] Transcriptional repressor that binds CpG islands in promoters where the DNA is methylated at position 5 of cytosine within CpG dinucleotides. Binding is abolished by the presence of 7-mG that is produced by DNA damage by methylmethanesulfonate (MMS). Acts as transcriptional repressor and plays a role in gene silencing by recruiting AFT7IP, which in turn recruits factors such as the histone methyltransferase SETDB1. Probably forms a complex with SETDB1 and ATF7IP that represses transcription and couples DNA methylation and histone 'Lys-9' trimethylation. Isoform 1 and isoform 2 can also repress transcription from unmethylated promoters.<ref>PMID:9207790</ref> <ref>PMID:10454587</ref> <ref>PMID:9774669</ref> <ref>PMID:10648624</ref> <ref>PMID:12711603</ref> <ref>PMID:12665582</ref> <ref>PMID:12697822</ref> <ref>PMID:14610093</ref> <ref>PMID:15327775</ref> <ref>PMID:14555760</ref> | ||

+ | The CXXC domain, first identified as the reader of unmodified CpG dinucleotide, plays important roles in epigenetic regulation by targeting various activities to CpG islands. Here we systematically measured and compared the DNA-binding selectivities of all known human CXXC domains by different binding assays, and complemented the existing function-based classification of human CXXC domains with a classification based on their DNA selectivities. Through a series of crystal structures of CXXC domains with DNA ligands, we unravel the molecular mechanisms of how these CXXC domains, including single CXXC domains and tandem CXXC-PHD domains, recognize distinct DNA ligands, which further supports our classification of human CXXC domains and also provides insights into selective recruitment of chromatin modifiers to their respective targets via CXXC domains recognizing different genomic DNA sequences. Our study facilitates the understanding of the relationship between the DNA-binding specificities of the CXXC proteins and their biological functions. | ||
