DESCRIPTION

Also known as MCM6_DROME, Mcm6. Acts as component of the Mcm2-7 complex (Mcm complex) which is the putative 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 neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differentially to the complex helicase activity Required for DNA replication and cell proliferation. Required for mitotic cycles, endocycles, and the special S phase associated with the amplification of chorion genes; has a role in origin unwinding or fork elongation at chorion loci. Component of the Mcm2-7 complex. The complex forms a toroidal hexameric ring with the proposed subunit order Mcm2-Mcm6-Mcm4-Mcm7-Mcm3-Mcm5 (Probable). The heterodimers of Mcm4/Mcm6 and Mcm3/Mcm5 interact with Mcm2 and Mcm7.
