Previous GeneCards Identifiers for MBD3 Gene
DNA methylation is the major modification of eukaryotic genomes and plays an essential role in mammalian development. This gene belongs to a family of nuclear proteins which are characterized by the presence of a methyl-CpG binding domain (MBD). The encoded protein is a subunit of the NuRD, a multisubunit complex containing nucleosome remodeling and histone deacetylase activities. Unlike the other family members, the encoded protein is not capable of binding to methylated DNA. The protein mediates the association of metastasis-associated protein 2 with the core histone deacetylase complex. Alternative splicing results in multiple transcript variants of this gene.

GeneCards Summary for MBD3 Gene
MBD3 (Methyl-CpG Binding Domain Protein 3) is a Protein Coding gene. Among its related pathways are Gene Expression and Regulation of TP53 Activity. Gene Ontology (GO) annotations related to this gene include chromatin binding and RNA polymerase II proximal promoter sequence-specific DNA binding. An important paralog of this gene is MBD2.
UniProtKB/Swiss-Prot for MBD3 Gene
Acts as transcriptional repressor and plays a role in gene silencing. Does not bind to DNA by itself (PubMed:12124384). Binds to DNA with a preference for sites containing methylated CpG dinucleotides (in vitro). Binds to a lesser degree DNA containing unmethylated CpG dinucleotides (PubMed:24307175). Recruits histone deacetylases and DNA methyltransferases.
