  • 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.
  • Tissue specificity

    Widely expressed.
  • Sequence similarities

    Contains 3 CXXC-type zinc fingers.
    Contains 1 MBD (methyl-CpG-binding) domain.
  • 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.
  • Post-translational

    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.
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Nucleus speckle. Chromosome. 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.

Customer reviews and Q&As


Thank you for contacting us.

The binding with methylated DNA is related to the peptide ab4918.Please chek this is not a prtoein it is a blocking peptide whihc was used to producty antibody ab2846. This is not a fucntional peptide.

The other proteins are full length (ab152513) is full length protein whih chas been tested in WB, SDS-PAGE and ELISA. These applicaiotn doe snot involve any kind of binding with DNA so I am sorry we will not be able to comment on the binding specificity of this protein.

We unfortunaltely do not have Biotin conjugated proteins avialable.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
