Did you know?
The protein encoded by this gene is one of the highly conserved mini-chromosome maintenance proteins (MCM) that are essential for the initiation of eukaryotic genome replication. 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. The MCM complex consisting of this protein and MCM… WebMCM3/5 can inhibit the activity of MCM4/6/7 helicase, while MCM2 stabilizes the interaction between MCM3/5 and MCM4/6/7. 23,24 In addition to participating in DNA replication, MCM proteins also play an important role in RNA transcription, chromatin reconstruction, and maintaining gene homeostasis. 25,26 In the clinic, MCM proteins have been …
Web5 jan. 2024 · Replication licensing in eukaryotes begins with the recruitment of two minichromosome maintenance (MCM) 2–7 complexes onto duplex DNA by the origin recognition complex (ORC) in an ATP-dependent manner. 1,2 The two hexameric MCM rings are loaded one at a time into a head-to-head double hexamer (DH) configuration … Web15 jul. 2024 · The DNA translocation activity of the minichromosome maintenance (MCM) complex powers DNA strand separation of the replication forks of eukaryotes and …
Web12 apr. 2024 · There are approximately 500 known origins of replication in the yeast genome, and the process by which DNA replication initiates at these locations is well understood. In particular, these sites are made competent to initiate replication by loading of the Mcm replicative helicase prior to the start of S phase; thus, "a site to which MCM … Web8 feb. 2016 · Moreover, MCM SUMOylation levels oscillated during the cell cycle in a manner opposite to those of MCM phosphorylation, suggesting that MCM SUMOylation is an inhibitory marker for replication.
WebINTRODUCTION. In the early 1980s, Bik-Kwoon Tye's laboratory carried out a general screen for Saccharomyces cerevisiae mutants that had defects in maintaining a simple minichromosome. Several of the MCM genes showed were paralogues and shared a role in DNA replication. They were the founding members of a conserved protein family …
Web8 mrt. 2024 · MCM-DHs that do not initiate replication are dislodged from DNA during replication. In Saccharomyces cerevisiae, origins are genetically defined by specific DNA sequences ( Marahrens and Stillman, 1992 ).
