ターゲット情報

  • 機能
    Required for genome wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. It modifies DNA in a non-processive manner and also methylates non-CpG sites. May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1. Plays a role in paternal and maternal imprinting. Required for methylation of most imprinted loci in germ cells. Acts as a transcriptional corepressor for ZNF238. Can actively repress transcription through the recruitment of HDAC activity.
  • 組織特異性
    Highly expressed in fetal tissues, skeletal muscle, heart, peripheral blood mononuclear cells, kidney, and at lower levels in placenta, brain, liver, colon, spleen, small intestine and lung.
  • 配列類似性
    Belongs to the C5-methyltransferase family.
    Contains 1 ADD domain.
    Contains 1 GATA-type zinc finger.
    Contains 1 PHD-type zinc finger.
    Contains 1 PWWP domain.
  • ドメイン
    The PWWP domain is essential for targeting to pericentric heterochromatin.
  • 翻訳後修飾
    Sumoylated; sumoylation disrupts the ability to interact with histone deacetylases (HDAC1 and HDAC2) and repress transcription.
  • 細胞内局在
    Nucleus. Cytoplasm. Accumulates in the major satellite repeats at pericentric heterochromatin.

  • Predicted band size : 101.5 kDa

    Western blot analysis of DNMT3a in HeLa silenced cells. Total cell extracts were prepared 48 h after electroporation and analyzed by immunoblot with ab2850.

  • DNMT3a is recruited to the DSB early during repair and is necessary for generation of L cells. HeLa cells were transfected with I-SceI (a meganuclease) and 24 h, 48 h or 7 days later, were fixed, collected, chromatin-extracted and subjected to ChIP analysis with ab2820. Figure 5B shows that DNMT3a is recruited to the I-SceI site 24 h after the onset of DSB formation and rapidly disappeared (48 h).

    Cells were fixed by adding formaldehyde directly in the culture medium to a final concentration of 1% for 10 min at RT and washed twice using ice cold PBS containing 1× protease inhibitor cocktail and 1 mM PMSF. Fixed cells were harvested and the pellet was resuspended in 200 µl of SDS Lysis Buffer. After 10 min incubation on ice, the lysates were sonicated. Sonicated samples were centrifuged and supernatants diluted 10-fold in the ChIP Dilution Buffer. An aliquot (1/50) of sheared chromatin was further treated with proteinase K, phenol/chloroform extracted and precipitated to determine DNA concentration and shearing efficiency (input DNA).

    Sheared chromatin was precleared,divided in two aliquots and incubated at 4°C for 16 h with 20 µl of protein-A/G agarose and 2 µg of ab2850 and nonimmune IgG. Agarose beads were washed and immunoprecipitated DNA was recovered and subjected to qPCR.
