Mini-chromosome maintenance complex-binding protein (MCMBP)

Associated component of the MCM complex that acts as a regulator of DNA replication. Binds to the MCM complex during late S phase and promotes the disassembly of the MCM complex from chromatin, thereby acting as a key regulator of pre-replication complex (pre-RC) unloading from replicated DNA.

Can dissociate the MCM complex without addition of ATP; likely acts by destabilizing interactions of every individual subunits of the MCM complex. Required for sister chromatid cohesion.
