|Calculated MW||66607 Da|
|Application & Usage||Western blot analysis (0.5-4 µg/ml). However, the optimal conditions should be determined individually. Cross activity to perforin of other species has not been determined.|
|Other Names||CXXC-type zinc finger protein 3, Methyl-CpG-binding protein MBD1, Protein containing methyl-CpG-binding domain 1|
|Formulation||100 µg (0.5 mg/ml) affinity purified rabbit anti- MBD1 polyclonal antibody in phosphate buffered saline (PBS), pH 7.2, containing 30% glycerol, 0.5% BSA, 5 mM EDTA and 0.01% thimerosal.|
|Handling||The antibody solution should be gently mixed before use.|
|Reconstitution & Storage||-20 °C|
|Precautions||MBD1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||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.|
|Cellular Location||Nucleus. Nucleus matrix. Nucleus speckle. Chromosome. Note=Colocalizes with the Ten-1 ICD form of TENM1 in foci associated with the nuclear matrix (By similarity). 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.|
|Tissue Location||Widely expressed.|

The MBD family of proteins includes MeCP2, MBD1, MBD2, MBD3 and MBD4. MBD1 (methyl-CpG binding domain protein 1) binds to methylated CpG sites and represses gene transcription. MBD1 is recruited to both methylated and non-methylated CpGs by separate domains: the CXXC domain targets the protein to non-methylated CpGs whereas the MBD domain targets the protein to methylated CpG. MBD1 may also interact with histone methyltransferase SETDB1 to repress transcription.
