Sen1 Is Recruited to Replication Forks via Ctf4 and Mrc1 and Promotes Genome Stability.
Title: Sen1 Is Recruited to Replication Forks via Ctf4 and Mrc1 and Promotes Genome Stability.
Here the authors show that Ctf4 tightly dimerizes CMG helicase, with an extensive interface involving Psf2, Cdc45, and Sld5. Interestingly, Ctf4 binds only one Pol alpha-primase. Thus, Ctf4 may have evolved as a trimer to organize two helicases and one Pol alpha-primase into a replication factory.
Title: Ctf4 organizes sister replisomes and Pol α into a replication factory.
ur results support a model whereby parental (H3-H4)2 complexes displaced from nucleosomes by DNA unwinding at replication forks are transferred by the CMG-Ctf4-Polalpha complex to lagging-strand DNA for nucleosome assembly at the original location.
Title: The Mcm2-Ctf4-Polα Axis Facilitates Parental Histone H3-H4 Transfer to Lagging Strands.
Ctf4 as a key regulator of DNA double strand end resection at arrested forks. End resection also occurs during physiological rDNA amplification even in the presence of Ctf4. Suppression of end resection is thus important for protecting DSBs at arrested forks from chromosome rearrangements.
Title: Ctf4 Prevents Genome Rearrangements by Suppressing DNA Double-Strand Break Formation and Its End Resection at Arrested Replication Forks.
The Chl1 helicase facilitates replication fork progression under conditions of nucleotide depletion, partly independently of Ctf4 interaction.
Title: Ctf4 Links DNA Replication with Sister Chromatid Cohesion Establishment by Recruiting the Chl1 Helicase to the Replisome.
Ctf4-dependent recruitment of Dna2/Tof2 couples other processes to DNA synthesis, including rDNA copy-number regulation.
Title: Ctf4 Is a Hub in the Eukaryotic Replisome that Links Multiple CIP-Box Proteins to the CMG Helicase.
Ctf4 is an essential member of the H3 lysine 56 acetylation pathway.
Title: Replisome function during replicative stress is modulated by histone h3 lysine 56 acetylation through Ctf4.
Data indicate that a defective DNA polymerase alpha (Polalpha)/DNA primase/chromatin-binding protein Ctf4 complex causes unscheduled strand annealing and fork reversal.
Title: Error-free DNA damage tolerance and sister chromatid proximity during DNA replication rely on the Polα/Primase/Ctf4 Complex.
Ctf4 can couple two molecules of Pol alpha to one CMG helicase within the replisome, providing a new model for lagging-strand synthesis in eukaryotes that resembles the emerging model for the simpler replisome of Escherichia coli
Title: A Ctf4 trimer couples the CMG helicase to DNA polymerase α in the eukaryotic replisome.
These data indicate that Ctf4p facilitates Mcm10p to promote the DNA replication.
