ターゲット情報

  • 機能

    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.

  • 組織特異性

    Widely expressed.

  • 配列類似性

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

  • ドメイン

    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.

  • 翻訳後修飾

    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.

  • 細胞内局在

    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.

    Question

    I have a question about two antibodies against MBD1 you offer. The catalog number for the first one is ab3753 and the other is ab2846 both detect the same protein with all his isoforms, but the molecular weight is very different. The first one ab3753 shows a band at 60kDa [your website says: Synthetic peptide: KQEPPDPEEDKEENKDDSAS (Human).This represents the C-terminal amino acids of all human MBD 1 isoforms. WB: Use at a dilution of 1/1000. Detects a band of approximately 60 kDa (predicted molecular weight: 57.6 kDa)]. and the other ab2846 at 83kDa [your website: Synthetic peptide: C-RSKDLKKPGARKQ, corresponding to amino acids 593-605 of Human MBD 1 WB: Use at a concentration of 2 - 5 ?g/ml. Detects a band of approximately 83 kDa (predicted molecular weight: 83 kDa)]. I hope you are able to explain this.

    Answer

    Thank you for your enquiry and for your patience. I have been looking into the issue that you have raised. Both ab3753 and ab2846 are originated outside Abcam and by two different sources. The originator of ab2846 said that all evidence that they have shows this antibody detecting a band at ~83 kDa. The SwissProt database link does say the molecular weight is 57.6 kDa. Ab2846 was only tested on recombinant MBD1 protein which may be the reason for the different molecular weights in the antibodies. I'm still investigating this issue and will let you of any additional information that I obtain.
