CC -!- FUNCTION: Regulatory subunit for CDC7 which activates its kinase
CC activity thereby playing a central role in DNA replication and cell
CC proliferation. Required for progression of S and M phases. The complex
CC CDC7-DBF4B selectively phosphorylates MCM2 subunit at 'Ser-40' and then
CC is involved in regulating the initiation of DNA replication during cell
CC cycle. {ECO:0000269|PubMed:12065429, ECO:0000269|PubMed:15668232,
CC ECO:0000269|PubMed:17062569}.
CC -!- SUBUNIT: Forms a complex with CDC7. Note that CDC7 forms distinct
CC complex either with DBF4/DBF4A or DBF4B. Such complexes are stable upon
CC replication stress.
