The hexameric protein complex formed by MCM proteins is a key component of the pre-replication complex (pre-RC) and may be involved in the formation of replication forks and in the recruitment of other DNA replication-related proteins. This protein forms a complex with MCM4, 6, and 7, and has been shown to regulate the helicase activity of the ...
The minichromosome maintenance protein complex (MCM) is a DNA helicase essential for genomic DNA replication. Eukaryotic MCM consists of six gene products, Mcm2–7, which form a heterohexamer. [1][2] As a critical protein for cell division, MCM is also the target of various checkpoint pathways, such as the S-phase entry and S-phase arrest ...
Electronic warfare. & decoys. see text. Armament. six M2HB .50 cal. machine guns, four M240B 7.62mm machine guns, two Mk 19 grenade launchers. USS Defender (MCM-2) was an Avenger -class mine countermeasures ship in the service of the United States Navy. She entered service in September 1989 and was decommissioned in October 2014.
The catalytic core of the helicase is composed of six minichromosome maintenance (Mcm2-7) proteins, forming a hexameric ring. Away from DNA, the Mcm2-7 proteins form a single heterohexamer and are loaded in an inactive form at origins of DNA replication as a head-to-head double hexamers around double-stranded DNA.
The MCM complex consisting of MCM6 (this protein) and MCM2, 4 and 7 possesses DNA helicase activity, and may act as a DNA unwinding enzyme.The hexameric protein complex formed by the MCM proteins is a key component of the pre-replication complex (pre-RC) and may be involved in the formation of replication forks and in the recruitment of other DNA replication related proteins.

A pre-replication complex (pre-RC) is a protein complex that forms at the origin of replication during the initiation step of DNA replication. Formation of the pre-RC is required for DNA replication to occur. Complete and faithful replication of the genome ensures that each daughter cell will carry the same genetic information as the parent cell.
Control of chromosome duplication. Overview of chromosome duplication in the cell cycle. In cell biology, eukaryotes possess a regulatory system that ensures that DNA replication occurs only once per cell cycle . A key feature of the DNA replication mechanism in eukaryotes is that it is designed to replicate relatively large genomes rapidly and ...
