ORC2 (human)

ORC2 Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent, however specific DNA sequences that define origins of replication have not been identified so far. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication. ORC is composed of six subunits. In human, ORC is cell cycle-dependent regulated: it is sequentially assembled at the exit from anaphase of mitosis and disassembled as cells enter S phase. Interacts with DBF4. Interacts with MCM10. Belongs to the ORC2 family. Note: This description may include information from UniProtKB.
