This gene encodes a protein which is a component of the hexameric minichromosome maintenance (MCM) complex which regulates initiation and elongation of DNA. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]
Function:
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; probably acts by destabilizing interactions of each individual subunits of the MCM complex. Required for sister chromatid cohesion.
Subunit:
Interacts with the MCM complex: associates with the MCM3-7 complex which lacks MCM2, while it does not interact with the MCM complex when MCM2 is present (MCM2-7 complex). Interacts with the RPA complex, when composed of all RPA1, RPA2 and RPA3 components, but not with RPA1 or RPA2 alone.
Subcellular Location:
Nucleus. Note: Associates with chromatin. Highly associated with chromatin in G1/S and S phases, reduced binding to chromatin in G2, and further decreased binding in early M phase. It then reassociates with chromatin in late M phase. Dissociates from chromatin later than component of the MCM complex.
Similarity:
Belongs to the MCMBP family.
