DBF4 DBF4 a regulatory subunit of the cell-cycle and genome duplication kinase Cdc7. DBF4 recruits the catalytic subunit CDC7 to MCM2 and to origins of replication. Its expression varies during the cell cycle: it is low in G1, increases during G1-S, and remains high during S and G2-M. Cdc7- DBF4B interacts physically with Mcm2 and phosphorylates Mcm2 and three other members of the Mcm family. Has a postreplicative function in meiosis. Interacts with CDC5 during meiosis to promote double-strand breaks and monopolar spindle orientation. Inhibits CDC5 activity during mitosis through direct binding to its PBD.
