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.
Belongs to the ORC3 family.
Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylated upon DNA damage, probably by ATM or ATR.
