Disease relevance of MBD1

  • This is the first report demonstrating that CXXC sequence containing MBD1 is overexpressed and can be the major factor of hypermethylated chromatin segments through HDAC1/2 translocation and histone deacetylation in human prostate cancer [1].
  • The MBD1 genotype was determined in 432 lung cancer patients and in 432 healthy control subjects who were frequency matched for age and gender [2].
  • To evaluate this hypothesis, we examined common variants in 12 genes coding for DNA methyltransferases (DNMT), histone acetyltransferases, histone deacetyltransferases, histone methyltrasferases and methyl-CpG binding domain proteins, for association with breast cancer in a large case-control study (N cases = 4474 and N controls = 4580) [3].
  • RFT expressed in some glioma cell lines, U138MG and T98G, but neither in U87MG nor U251MG [4].
  • The defect was CD8 T cell intrinsic, because memory cell development was also delayed when MBD2(-/-) CD8 T cells were adoptively transferred into SCID mice [5].
 

Psychiatry related information on MBD1

  • The knowledge of additional existing MBD proteins and their expression pattern is important in the context of Rett syndrome [6].
  • The classification of field dependence-independence was based on predetermined RFT and EFT standards [7].
  • Regulatory focus theory (RFT; Higgins, 1997) predicts that individual differences in the strength of promotion (ideal) and prevention (ought) orientations emerge from patterns of parent/child interactions that emphasize making good things happen versus keeping bad things from happening [8].
 

High impact information on MBD1

 

Biological context of MBD1

 

Anatomical context of MBD1

  • Previous work has shown that MBD1 binds to methylated sites in vivo and in vitro and can repress transcription from methylated templates in transcription extracts and in cultured cells [17].
  • For CXXC sequence containing MBD1, both protein and mRNA were expressed in cancer cell lines, cancer tissues, BPH-1 cell line, and BPH tissues [1].
  • The intracellular domain of teneurin-1 interacts with MBD1 and CAP/ponsin resulting in subcellular codistribution and translocation to the nuclear matrix [18].
  • Sex-specific windows for high mRNA expression of DNA methyltransferases 1 and 3A and methyl-CpG-binding domain proteins 2 and 4 in human fetal gonads [19].
  • A synthetic RNA encoding enhanced green fluorescence protein fused to the methyl-CpG-binding domain and nuclear localization signal of human MBD1 was microinjected into metaphase II-arrested or fertilized oocytes, and the localization of methylated DNA was monitored by live cell imaging [20].
 

Associations of MBD1 with chemical compounds

  • The mechanism is likely to involve deacetylation, since the deacetylase inhibitor trichostatin A can overcome MBD1-mediated repression [17].
  • Methyl CpG-binding protein 1 (MBD1), which functions as a transcriptional repressor, was identified as a strong p59 OASL interactor [21].
  • An R269C mutation that resulted in the addition of cysteine near a cysteine rich region was found in the MBD1 gene in one patient [22].
  • We further demonstrate that knockdown of MBD1 by specific small interfering RNAs significantly increases cell sensitivity to MMS [23].
  • Here we show that histone H3 methylase Suv39h1 and the methyl lysine-binding protein HP1 directly interact with MBD of MBD1 in vitro and in cells [24].
  • Use of the DNA demethylating agent 5-azadeoxycytidine abolished the formation of MBD1 foci but not PcG foci [25].
 

Physical interactions of MBD1

 

Regulatory relationships of MBD1

 

Other interactions of MBD1

  • PML-RARalpha recruits MBD1 to its target promoter through an HDAC3-mediated mechanism [14].
  • MeCP2, MBD1 and MBD2 can also repress transcription [29].
  • In the present study, we have investigated the significance of MBD, CXXC, and the C-terminal transcriptional repression domain (TRD) in MBD1 [15].
  • These findings link the p59 OASL with MBD1 transcriptional control in the context of an interferon-stimulated cell, and provide the basis for future studies to examine the functional role of this interaction [21].
  • Thus, the deacetylase-dependent pathway by which MBD1 actively silences methylated genes is likely to be different from that utilized by the methylation-dependent repressors MeCP1 and MeCP2 [17].
