Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

TICRR/TRESLIN is an essential metazoan DNA replication initiation factor that acts at the pre-initiation complex (pre-IC) assembly step to load CDC45 onto licensed origins, and its depletion abolishes chromosomal DNA replication (PMID:20116089, PMID:20080954). TRESLIN binds chromatin independently of TopBP1, but its association with the N-terminal BRCT repeats of TopBP1 requires CDK2-cyclin E phosphorylation at conserved CDK consensus sites (S1000/T968 in humans), and this phospho-dependent TRESLIN–TopBP1 interaction is the rate-limiting event for CDC45 loading and origin firing (PMID:20116089, PMID:21700459, PMID:21646402). TRESLIN functions as a stable elongated heterotetramer with MTBP, which contributes a DNA-binding C-terminal domain required for chromatin localization and CDC45 loading; reconstitution requires both proteins together, and the phospho-TRESLIN–MTBP complex is limiting for S-phase duration and origin number (PMID:28877985, PMID:25737283, PMID:34699733). Loading of TRESLIN–MTBP onto phosphorylated MCM2-7 double hexamers is driven by DDK and opposed by RIF1–PP1, an antagonism that defines initiation zones and replication timing, with CDK cooperating with DDK to drive the TopBP1 interaction at the pre-IC step (PMID:41331242, PMID:34699733). TRESLIN abundance and activity are tightly controlled across the cell cycle by CRL4-DTL- and PCNA-dependent proteasomal degradation upon S-phase entry, which moderates active origin number [PMID:34534348, PMID:bio_10.1101_2025.06.10.657920]. The interaction is negatively regulated during replication stress by Chk1, which binds a C-terminal TRESLIN domain (TRCT), directly phosphorylates TRESLIN, and reduces its CDK-site phosphorylation to dissociate TopBP1 and suppress origin firing; loss of Chk1–TRESLIN binding elevates origin firing even in an unperturbed S phase (PMID:25557548, PMID:21700459, PMID:35231445). TRESLIN additionally couples replication initiation to checkpoint signaling by stimulating TopBP1-dependent ATR-mediated Chk1 phosphorylation, and through dynamic, transient action at origins it implements an ATR/Chk1-independent monitoring system that prevents premature G2 entry (PMID:23696651, PMID:36049481).

2010 Treslin (TICRR) associates with TopBP1 in Xenopus egg extracts and human cells, and is required for loading of Cdc45 onto chromatin. Depletion of Treslin strongly inhibits chromosomal DNA replication. Treslin binds chromatin independently of TopBP1, but Treslin-TopBP1 association requires Cdk2 activity and is necessary for Cdc45 loading. Immunodepletion from Xenopus egg extracts, co-immunoprecipitation, siRNA knockdown in human cells, chromatin fractionation Cell High 20116089
2010 TICRR (ticrr) associates with TopBP1 via BRCT motifs essential for TopBP1's replication and checkpoint functions, and ticrr deficiency disrupts chromatin binding of pre-initiation complex (pre-IC) components without affecting pre-replication complex (pre-RC) loading, placing TICRR at the pre-IC assembly step. Zebrafish genetic screen, co-immunoprecipitation, chromatin fractionation, morpholino knockdown Genes & development High 20080954
2011 Treslin/TICRR contains two conserved CDK phosphorylation sites (orthologous to yeast Sld3 CDK sites) that are essential for DNA replication. Phosphorylation of these sites mediates interaction with the N-terminal pair of BRCT repeats in TopBP1 (ortholog of yeast Dpb11). Replication stress prevents this interaction via the Chk1 checkpoint kinase. Mutagenesis of CDK sites, co-immunoprecipitation, siRNA knockdown with replication assays, sequence conservation analysis Current biology : CB High 21700459
2011 Treslin is phosphorylated by Cdk2-cyclin E at a conserved CDK consensus site (S976 in Xenopus, S1000 in humans). This phosphorylation is required for effective association with TopBP1 and for DNA replication. A non-phosphorylatable mutant shows severely diminished TopBP1 binding and replication deficiency. In vitro kinase assay with recombinant Cdk2-cyclin E, site-directed mutagenesis, co-immunoprecipitation, human cell replication assays The Journal of cell biology High 21646402
2014 Chk1 associates specifically with a C-terminal domain of Treslin (TRCT domain). This interaction enables Chk1-catalyzed phosphorylation of Treslin. Abolishing the Treslin-Chk1 interaction results in elevated replication initiation during an unperturbed S phase due to enhanced Cdc45 loading, revealing a Chk1 role in suppressing origin firing during normal S phase. Co-immunoprecipitation, TRCT domain mutagenesis, EdU incorporation assays, Cdc45 chromatin loading analysis Molecular cell High 25557548
2013 Treslin stimulates ATR-mediated phosphorylation of Chk1 both in vitro and in vivo in a TopBP1-dependent manner, and the phosphorylation state of Treslin at Ser-1000 is important for this checkpoint activity, indicating Treslin is a dual replication/checkpoint protein. In vitro ATR kinase assay, cell-based checkpoint assays, phosphorylation site mutagenesis The Journal of biological chemistry Medium 23696651
2015 Overexpression of a phosphomimetic TICRR mutant (TICRR-TESE, mimicking CDK phosphorylation at two key residues) shortens S phase by increasing replication initiation. This effect requires the TICRR region necessary for interaction with MTBP (Mdm2-binding protein), demonstrating that phosphorylated TICRR is limiting for S-phase progression. Phosphomimetic mutant overexpression, EdU incorporation, DNA fiber analysis, replication cluster analysis in human cells Genes & development Medium 25737283
2017 MTBP (Mdm2-binding protein) is a binding partner of Treslin. Depletion of MTBP from Xenopus egg extracts co-depletes Treslin and abolishes DNA replication, which can only be rescued by recombinant Treslin-MTBP together, not either protein alone. MTBP contains a C-terminal domain (CTM) that binds double-stranded and G-quadruplex DNA, and CTM mutants are defective for chromatin localization and Cdc45 loading.

2017 Ensa (a substrate of Greatwall kinase) controls Treslin protein levels via the ubiquitin-proteasome pathway. Ensa knockdown reduces Treslin levels and extends S phase; this phenotype is rescued by Treslin overexpression. The Gwl/Ensa/PP2A-B55 pathway thus regulates S-phase duration by controlling Treslin degradation. siRNA knockdown, proteasome inhibitor treatment, rescue experiments with Treslin overexpression, flow cytometry Nature communications Medium 28785014
2017 Mutant p53 (contact-type, e.g. R273H) enhances the interaction between TopBP1 and Treslin and promotes DNA replication even when Cdk2 is inhibited, bypassing the normal CDK requirement for Treslin-TopBP1 interaction.

2021 MTBP forms an elongated tetramer with Treslin containing two molecules of each protein. Treslin-MTBP is rate-limiting for replication initiation. DDK activity both increases and strengthens the interaction of Treslin-MTBP with licensed chromatin, and cooperates with CDK to drive Treslin-MTBP interaction with TopBP1 at the pre-IC formation step.

2021 TICRR/TRESLIN protein levels are high in G1 and decrease upon S-phase entry via CRL4-DTL E3 ubiquitin ligase-dependent proteasomal degradation. This mechanism moderates TICRR levels to control the number of active origins during S phase. Cell cycle synchronization, immunoblotting, siRNA screens targeting E3 ligase components, proteasome inhibitor treatment Nucleic acids research Medium 34534348
2020 MTBP (and hence the Treslin-MTBP complex) binds to at least 30,000 sites in the human genome, preferentially at regions of open chromatin containing transcriptional-regulatory elements (promoters, enhancers, super-enhancers) with nucleosome-free DNA (G-quadruplex or AP-1 motifs) and H3K4me2-marked nucleosomes.

2022 TRESLIN-MTBP acts transiently at pre-replication complexes to initiate origin firing and is released after CDC45 recruitment. The dynamic behavior of TRESLIN-MTBP implements a monitoring system that senses the rate of origin firing and the decline of active origins in late S phase, preventing premature entry into G2 independently of ATR/CHK1 kinases.

2022 Chk1 regulates the Treslin-TopBP1 interaction through multiple mechanisms during replication stress: (1) Chk1-dependent decrease in CDK activity reduces phosphorylation of Treslin T968 (but not S1000), and (2) Chk1 directly phosphorylates additional sites on Treslin including S1114, both contributing to dissociation of TopBP1 from Treslin and suppression of origin firing.

2018 DUE-B interacts with Treslin in HeLa cells in a cell-cycle-regulated manner (peaking as cells exit G1). The conserved C-terminal domain of DUE-B is required for its binding to TopBP1, Treslin, Cdc45, and MCM2-7, and for efficient chromatin loading of Treslin, Cdc45, and TopBP1. The DUE-B-Treslin interaction is required for Cdc45 loading onto chromatin. Co-immunoprecipitation, domain mutagenesis, chromatin fractionation, cell cycle synchronization The Journal of biological chemistry Medium 30037903
2017 CKS proteins (Cks1, Cks2) enhance the ability of Cdk2 to phosphorylate Treslin in vitro, promoting replication checkpoint recovery. CKS binding-defective mutants retain the ability to stimulate Treslin phosphorylation. Silencing of Cks1/Cks2 decreases Treslin phosphorylation in vivo, and CKS overexpression prevents checkpoint-dependent dephosphorylation of Treslin. In vitro kinase assay, siRNA knockdown, CKS mutant overexpression, phospho-Treslin immunoblotting Molecular and cellular biology Medium 28739856
2025 TRESLIN-MTBP is a key limiting firing factor for replication initiation in human cells. Its loading onto phosphorylated MCM2-7 double hexamer (MCM-DH) is controlled by opposing phosphorylation events on MCM-DH by DDK (promoting TRESLIN-MTBP loading) and RIF1-Protein Phosphatase 1 (opposing loading), which determines initiation zones and establishes replication timing. Genome-wide mapping of TRESLIN-MTBP and MCM, kinase/phosphatase inhibitor treatments, chromatin fractionation in human cells Nature communications Medium 41331242
2025 During G1, MTBP depends on TRESLIN for proper chromatin association, but not during S phase, suggesting two distinct modes of TRESLIN-MTBP chromatin binding. Neither TRESLIN nor MTBP binding to chromatin during G1 requires licensed MCM origins. Cut&Run genomic binding mapping, cell cycle synchronization, Geminin-based MCM depletion, siRNA knockdown of TRESLIN/MTBP Genome biology Medium 40624716
2022 Sequence analysis and structural homology modeling revealed that Treslin/TICRR contains a conserved Ku70-homologous β-barrel fold in its middle domain (M domain), and a von Willebrand factor type A domain in the CIT region. The M domain, Sld3-Treslin domain, and TopBP1/Dpb11 interaction domain together constitute the Sld3-homologous core. Domain mutants expressed in human cells indicate all three Sld3-core domains plus non-conserved terminal domains are required for proper origin firing.

2025 WEE1 kinase inhibition during S phase increases CDK activity, which blocks PCNA-dependent proteasomal degradation of TRESLIN and enhances chromatin association of TRESLIN and MTBP, leading to elevated helicase recruitment and dormant origin firing. A conserved sequence within TRESLIN is required for this CDK-sensitive degradation.
