ターゲット情報

  • 機能
    The reaction catalyzed by topoisomerases leads to the conversion of one topological isomer of DNA to another.
  • 関連疾患
    Note=A chromosomal aberration involving TOP1 is found in a form of therapy-related myelodysplastic syndrome. Translocation t(11;20)(p15;q11) with NUP98.
  • 配列類似性
    Belongs to the eukaryotic type I topoisomerase family.
  • 翻訳後修飾
    Sumoylated. Lys-117 is the main site of sumoylation. Sumoylation plays a role in partitioning TOP1 between nucleoli and nucleoplasm. Levels are dramatically increased on camptothecin (CPT) treatment.
  • 細胞内局在
    Nucleus > nucleolus. Nucleus > nucleoplasm. Diffuse nuclear localization with some enrichment in nucleoli. On CPT treatment, cleared from nucleoli into nucleoplasm. Sumolyated forms found in both nucleoplasm and nucleoli.

Anti-Topoisomerase I antibody 画像

  • ICC/IF image of ab28432 stained MCF-7 cells. The cells were 4% formaldehyde 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 (ab28432, 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.

We have not tested ab28432 for mouse reactivity, but is likely that most topoisomerase antibodies, including ab28432, that react with human samples will react with mouse samples, given the 96% identity shared by the two proteins. This is based on align...
