      Background InformationDNA methylation, or the addition of methyl groups to cytosine bases in the dinucleotide CpG, regulates gene expression and is critical for proper development. Human proteins MECP2, MBD1, MBD2, MBD3, and MBD4 comprise a family of nuclear proteins related by the presence in each of a methyl-CpG binding domain (MBD). Each of these proteins, with the exception of MBD3, is capable of binding specifically to methylated DNA. MECP2, MBD1 and MBD2 can also repress transcription from methylated gene promoters. MBD1 has been shown to play a role in chromatin modification through interaction with the histone H3K9 methyltransferase SETDB1. Five transcript variants of the MBD1 are generated by alternative splicing resulting in protein isoforms that each contain one MBD domain, two to three cysteine-rich (CXXC) domains, and some differences in the COOH terminus. MBD1, MBD2, MBD3, and MBD4 are expressed in somatic tissues, but the expression of MBD1 and MBD2 is reduced or absent in embryonic stem cells, which are known to be deficient in MeCP1 activity.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a class IV histone deacetylase. The encoded protein is localized to the nucleus and may be involved in regulating the expression of interleukin 10. Alternative splicing results in multiple transcript variants.

      Transcript Variant: This variant (1) represents the longer transcript and encodes the longer isoform (1).

      Sequence Note: This RefSeq record was created from transcript and genomic sequence data to make the sequence consistent with the reference genome assembly. The genomic coordinates used for the transcript record were based on transcript alignments.

      UniProt Number
      UniProt SummaryFUNCTION: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.1 Ref.3 Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 Ref.21

      SUBUNIT STRUCTURE: Binds OASL, AFT7IP and AFT7IP2. Binds CHAF1A and the SUV39H1-CBX5 complex via the MBD domain. Binds MGP via the TRD domain. May be part of the MeCP1 complex. During DNA replication, it recruits SETDB1 to form a S phase-specific complex that facilitates methylation of H3 'Lys-9' during replication-coupled chromatin assembly and is at least composed of the CAF-1 subunit CHAF1A, MBD1 and SETDB1.

      SUBCELLULAR LOCATION: Nucleus speckle. Note= Nuclear, in a punctate pattern. Associated with euchromatic regions of the chromosomes, with pericentromeric regions on chromosome 1 and with telomeric regions from several chromosomes. Ref.1 Ref.3 Ref.8 Ref.9 Ref.12 Ref.21

      TISSUE SPECIFICITY: Widely expressed. Ref.1

      INDUCTION: Up-regulated by interferon. Ref.4

      DOMAIN:The methyl-CpG-binding domain (MBD) functions both in binding to methylated DNA and in protein interactions.

      The third CXXC-type zinc finger mediates binding to non-methylated CpG dinucleotides.

      The transcriptional repression domain (TRD) is involved in transcription repression and in protein interactions.

      PTM: Sumoylated with SUMO1 by PIAS1 and PIAS3. Sumoylation affects transcriptional silencing by preventing the interaction with SETDB1. In contrast, sumoylation may increase interaction with AFT7IP. Ref.16 Ref.17

      Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.16 Ref.15 Ref.18 Ref.19

      SEQUENCE SIMILARITY: Contains 3 CXXC-type zinc fingers.

      Contains 1 MBD (methyl-CpG-binding) domain.
