Target

  • Function

    Methylates CpG residues. Preferentially methylates hemimethylated DNA. Associates with DNA replication sites in S phase maintaining the methylation pattern in the newly synthesized strand, that is essential for epigenetic inheritance. Associates with chromatin during G2 and M phases to maintain DNA methylation independently of replication. It is responsible for maintaining methylation patterns established in development. DNA methylation is coordinated with methylation of histones. Mediates transcriptional repression by direct binding to HDAC2. In association with DNMT3B and via the recruitment of CTCFL/BORIS, involved in activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9.
  • Tissue specificity

    Ubiquitous; highly expressed in fetal tissues, heart, kidney, placenta, peripheral blood mononuclear cells, and expressed at lower levels in spleen, lung, brain, small intestine, colon, liver, and skeletal muscle. Isoform 2 is less expressed than isoform 1.
  • Sequence similarities

    Belongs to the C5-methyltransferase family.
    Contains 2 BAH domains.
    Contains 1 CXXC-type zinc finger.
  • Domain

    The N-terminal part is required for homodimerization and acts as a regulatory domain.
  • Post-translational
    modifications

    Sumoylated; sumoylation increases activity.
  • Cellular localization

    Nucleus.

      ab19905 was shown to recognize DNMT1 when DNMT1 knockout samples were used, along with additional cross-reactive bands. Wild-type and DNMT1 knockout samples were subjected to SDS-PAGE. Ab19905 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1 ug/ml and 1/10000 dilution respectively. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10010 dilution for 1 hour at room temperature before imaging.

      ab19905 specifically recognises Dnmt1 at 183 kDa in HeLa nuclear extracts (lane1), which is efficiently blocked using the immunising peptide (ab21999) (lane2).
    • Immunoprecipitation - Anti-Dnmt1 antibody (ab19905)
      Immunoprecipitation - Anti-Dnmt1 antibody (ab19905)
      Dnmt1 was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to Dnmt1 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
      The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
      Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab19905.

      ab19905 at a 1/200 dilution staining paraformaldehyde fixed asynchronous HeLa cells by ICC/IF. The antibody was incubated with the cells for 30 minutes and then bound antibody was detected using a Cy3 conjugated goat anti-rabbit antibody. Nuclei were visualised using DAPI staining. Ab19905 gives a pattern that is predominantly enriched within nuclei.

      Jurkat cells were incubated at 37°C for 5 days with vehicle control (0 µM) and different concentrations of hydralazine hydrochloride (ab120863). Decreased expression of DNMT1 (ab19905) in Jurkat cells correlates with an increase in hydralazine hydrochloride concentration, as described in literature.

      Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 20µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab19905 at 1 µg/ml and ab8227 at 1 µg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution.

      ICC/IF image of ab19905 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab19905, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 1% PFA fixed (10 min) Hek293, HepG2 and MCF7 cells at 1µg/ml.
