Anti-Mcm7 Antibody (Monoclonal, DCS-141), Carrier-free

Initiation of DNA replication is a complex process involving the concerted action of many proteins. The chromosome 7-linked gene referred to by Nakatsuru et al. as MCM2 has been designated MCM7. The MCM2-7 complex is comprised of 6 subunits, MCM2 through MCM7, and is a ring-shaped heterohexameric ATPase involved in DNA replication. MCM7 is located in 7q21.3-q22.1.

MCM7: Acts as component of the MCM2-7 complex (MCM complex)which is the putative replicative helicase essential for 'once percell cycle' DNA replication initiation and elongation ineukaryotic cells. The active ATPase sites in the MCM2-7 ring areformed through the interaction surfaces of two neighboringsubunits such that a critical structure of a conserved argininefinger motif is provided in trans relative to the ATP-binding siteof the Walker A box of the adjacent subunit. The six ATPase activesites, however, are likely to contribute differentially to thecomplex helicase activity. Required for S-phase checkpointactivation upon UV-induced damage.
