Application Abreviews Notes
ICC/IF Use a concentration of 1 µg/ml.
WB 1/500 - 1/1000. Detects a band of approximately 77 kDa (predicted molecular weight: 77 kDa).
ELISA 1/10000.


  • FunctionRegulatory subunit for CDC7 which activates its kinase activity thereby playing a central role in DNA replication and cell proliferation. Required for progression of S phase. The complex CDC7-DBF4A selectively phosphorylates MCM2 subunit at 'Ser-40' and 'Ser-53' and then is involved in regulating the initiation of DNA replication during cell cycle.
  • Tissue specificityHighly expressed in testis and thymus. Expressed also in most cancer cells lines.
  • Sequence similaritiesContains 2 BRCT domains.
    Contains 1 DBF4-type zinc finger.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localizationNucleus.

  • ICC/IF image of ab70134 stained HeLa cells. The cells were 100% methanol fixed (5 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 (ab70134, 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.
