Our Abpromise guarantee covers the use of ab26483 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 60 kDa (predicted molecular weight: 55 kDa).
ICC/IF Use a concentration of 1 µg/ml.


  • Function
    Required for full ubiquitin ligase activity of the anaphase promoting complex/cyclosome (APC/C) and may confer substrate specificity upon the complex. Is regulated by MAD2L1. In metaphase the MAD2L1-CDC20-APC/C ternary complex is inactive and in anaphase the CDC20-APC/C binary complex is active in degrading substrates.
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Belongs to the WD repeat CDC20/Fizzy family.
    Contains 7 WD repeats.
  • Developmental stage
    Synthesis is initiated at G1/S, protein level peaks in M phase and protein is abruptly degraded at M/G1 transition.
  • Post-translational
    Phosphorylated during mitosis, probably by maturation promoting factor (MPF). Phosphorylated by BUB1 at Ser-41; Ser-72; Ser-92; Ser-153; Thr-157 and Ser-161.
    Ubiquitinated and degraded by the proteasome during spindle assembly checkpoint. Deubiquitinated by USP44, leading to stabilize the MAD2L1-CDC20-APC/C ternary complex, thereby preventing premature activation of the APC/C.

    Predicted band size: 55 kDa

    ab26483 consistently detects a band at 55-60 kDa but we also see bands of ~35 and 70 kDa that appear with varying intensity in some of our extracts. We cannot find an explanation for this and are unsure of the nature of these crossreacting bands.
  • ICC/IF image of ab26483 stained human HEK 293 cells. The cells were PFA fixed (10 min), permabilised in PBS-T (20 min) and incubated with the antibody (ab26483, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. 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). DAPI was used to stain the cell nuclei (blue).
