Synthesis pass · prose summary of the discoveries below

MCM2 is a subunit of the heterohexameric MCM2-7 replicative helicase, essential for both the initiation and elongation phases of eukaryotic DNA replication, and serving dual roles as a histone H3-H4 chaperone that ensures symmetric parental histone inheritance during fork progression (PMID:2044961, PMID:10834843, PMID:30115746). During G1, ORC-Cdc6-Cdt1 loads MCM2-7 as a head-to-head double hexamer onto origin DNA, with the Mcm2-Mcm5 interface functioning as the DNA entry gate whose opening and closure are coupled to ATP hydrolysis and Cdt1 release (PMID:19896182, PMID:25085418, PMID:28191892). S-phase activation requires Mec1/ATR-dependent priming phosphorylation followed by DDK (Cdc7-Dbf4) phosphorylation of the MCM2 N-terminus—with Dbf4's HBRCT domain docking onto Mcm2 across the double-hexamer interface—to promote Cdc45-GINS recruitment and CMG complex assembly, converting the latent ring into an active helicase (PMID:9407029, PMID:35614055, PMID:33616038). Beyond replication, MCM2's histone-binding domain cooperates with ASF1 and FACT to recycle parental histones to lagging strands, supports stem cell differentiation by remodeling bivalent chromatin domains, and acts as a transcriptional repressor at cilia-inhibiting gene promoters in non-cycling cells to promote ciliogenesis (PMID:26167883, PMID:36354740, PMID:37850662, PMID:30329080).

2017 The yeast MCM hexamer and Cdt1-MCM heptamer adopt left-handed coil structures with a 10-15 Å gap between Mcm5 and Mcm2; Cdt1 wraps around the N-terminal regions of Mcm2, Mcm6, and Mcm4; the Mcm5 WHD occludes the central channel; these open-ring precursor structures suggest a spring-action model for helicase loading and origin melting. Cryo-EM structure determination of yeast MCM hexamer and Cdt1-MCM heptamer Nature structural & molecular biology High 28191894
2017 Single-molecule FRET and colocalization spectroscopy show that Mcm2-7 rings are open during initial DNA association and close sequentially (concomitant with Cdt1 release); Mcm2-7 ATP hydrolysis is coupled to ring closure and Cdt1 release; the first Mcm2-7 must load before the second can be recruited. Single-molecule FRET, colocalization single-molecule spectroscopy (CoSMoS) Nature structural & molecular biology High 28191892
2018 MCM2, as part of the replicative helicase, ensures symmetric inheritance of parental histone H3-H4 to both sister chromatids; histone-binding mutations in MCM2 increase leading-strand bias of parental histone segregation and exacerbate histone PTM asymmetry between sister chromatids. SCAR-seq (sister chromatid analysis of replication), histone PTM partition measurement in embryonic stem cells Science (New York, N.Y.) High 30115746
2018 O-GlcNAc transferase (OGT) stably interacts with multiple MCM2-7 subunits; all six MCM2-7 subunits are O-GlcNAcylated predominantly in the chromatin-bound fraction; OGT silencing decreases chromatin binding of MCM2, MCM6, and MCM7, and destabilizes MCM2/6 and MCM4/7 interactions in chromatin. Co-immunoprecipitation, mass spectrometry, siRNA silencing, chromatin fractionation Cellular and molecular life sciences : CMLS Medium 30069701
2019 A conserved Mcm4 motif is required for stable MCM2-7 double-hexamer formation; mutations permitting loading of two Mcm2-7 complexes but blocking double-hexamer stability demonstrate that double-hexamer formation is required for extensive origin DNA unwinding but not initial DNA melting or recruitment of Cdc45, GINS, or Mcm10. Single-molecule assays, biochemical reconstitution, kinetic analysis eLife High 31385807
2019 MCM2 has a non-replicative role in ciliogenesis in non-cycling human fibroblasts and zebrafish; MCM2 binds to transcription start sites of cilia-inhibiting genes in post-mitotic cells, and its loss promotes transcription of these genes, causing cilia shortening and centriole overduplication. ChIP, siRNA knockdown in non-cycling fibroblasts, zebrafish morpholino depletion, cilia length measurement Nucleic acids research Medium 30329080
2021 DDK phosphorylation of multiple sites on Mcm2-7 N-terminal tails modulates the number of Cdc45-tail-GINS (CtG) intermediates formed per Mcm2-7 in a first recruitment stage; higher CtG multiplicity increases the frequency of CMG formation in a second, inefficient conversion step. Single-molecule biochemical assays for CMG formation, phosphorylation site mutagenesis eLife High 33616038
2022 Cryo-EM and biochemical analysis shows that the Dbf4 HBRCT domain anchors DDK to Mcm2 as a docking point; this supports DDK binding across the MCM2-7 double-hexamer interface, allowing phosphorylation of Mcm4 on the opposite hexamer; DDK rotation around the Mcm2 anchor allows phosphorylation of Mcm2 and Mcm6. Cryo-EM, biochemical analysis, DDK-MCM2-7 interaction mapping Nature communications High 35614055
2022 MCMBP associates with MCM3 and is required for assembly of the MCM2-7 hexamer in human cells using nascent MCM3; acute MCMBP depletion reduces replication licensing; p53-null cells depleted of MCMBP enter S phase and accumulate DNA damage, while p53-positive cells arrest in G1. Auxin-inducible degron (AID) acute depletion, co-immunoprecipitation, flow cytometry, DNA damage markers eLife High 35438632
2022 Mcm2 histone-binding function is required for silencing of pluripotent genes and induction of lineage-specific genes during embryonic stem cell differentiation; Mcm2-2A mutation (defective in histone binding) reduces binding of Asf1a (a histone chaperone that partners with Mcm2 for nucleosome disassembly at bivalent chromatin), reduces Mcm2 binding at gene promoters including bivalent domains, and decreases chromatin accessibility at these sites in neural precursor cells.

2023 The N-terminus of Spt16 (FACT subunit) directly interacts with the replicative helicase MCM2-7 and facilitates formation of a ternary complex involving FACT, histone H3/H4, and the Mcm2 histone-binding domain; this interaction is required for efficient parental histone recycling and transfer to lagging strands during replication.
