High impact information on DBF4

 

Biological context of DBF4

  • Cdc7 kinase activity fluctuates during cell cycle, and this is mainly the result of oscillation of expression of the Dbf4 subunit [4].
  • Cdc7-Dbf4 kinase is conserved through evolution and regulates initiation and progression of DNA replication [3].
  • We report here the direct interaction of chromatin assembly factor 1 (CAF1), a key factor involved in histone deposition, with the replication kinase Cdc7-Dbf4 [5].
 

Regulatory relationships of DBF4

  • Cdc7 kinase is required for DNA replication and its kinase activity is cell cycle-regulated by its activation subunit Dbf4/ASK [6].
