Previous GeneCards Identifiers for MBD1 Gene
The protein encoded by this gene is a member of a family of nuclear proteins related by the presence of a methyl-CpG binding domain (MBD). These proteins are capable of binding specifically to methylated DNA, and some members can also repress transcription from methylated gene promoters. This protein contains multiple domains: MBD at the N-terminus that functions both in binding to methylated DNA and in protein interactions; several CXXC-type zinc finger domains that mediate binding to non-methylated CpG dinucleotides; transcriptional repression domain (TRD) at the C-terminus that is involved in transcription repression and in protein interactions. Numerous alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Feb 2011]
GeneCards Summary for MBD1 Gene
MBD1 (Methyl-CpG Binding Domain Protein 1) is a Protein Coding gene. Diseases associated with MBD1 include trigeminal neuralgia and cutaneous lupus erythematosus. Among its related pathways are Cell Cycle, Mitotic and Cell Cycle, Mitotic. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and methyl-CpG binding.
UniProtKB/Swiss-Prot for MBD1 Gene
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.
