This is the winged helix domain (WHD) found at the C-terminal of MCM4 [1-3]. Upon ssDNA binding the MCM5-WHD moves out of the central channel and becomes disordered, the MCM6-WHD moves backward and away from the channel, and the MCM4-WHD now partially occludes the channel opening. These changes enable CMG (Cdc45, Mcm2-7, GINS, the eukaryotic replicative helicase) to encircle dsDNA, and is consistent with reports that showed the MCM2-7 matures into two fully assembled CMGs on dsDNA before origin DNA unwinding occurs [3].

MCM3 is a minichromosome maintenance (MCM) protein, a component of the MCM2-7 complex (MCM complex) which is the replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the MCM2-7 ring are formed through the interaction surfaces of two neighbouring subunits [1].
