(Submitter supplied) Cdc7 kinase is known to initiate DNA replication, but it is unknown where Cdc7 is found within the genome. We modified the Calling Cards method that uses the Ty5 retrotransposon to investigate Cdc7 binding in the genome. The Ty5 retrotransposon is inserted into the genome by DNA transcription factors or replication factors binding within the genome. We find that Cdc7 inserts Ty5 transposons throughout chromosomes and furthermore creates more Ty5 insertions into regions of DNA that are known to replicate early. more...

(Submitter supplied) Centromeres play several important roles in ensuring proper chromosome segregation. Not only do they promote kinetochore assembly for microtubule attachment, but they also support robust sister chromatid cohesion at pericentromeres and facilitate replication of centromeric DNA early in S phase. However, it is still elusive how centromeres orchestrate all these functions at the same site. Here we show that the budding yeast Dbf4-dependent kinase (DDK) accumulates at kinetochores in telophase, facilitated by the Ctf19 kinetochore complex. more...

(Submitter supplied) Initiation of eukaryotic DNA replication requires temporal separation of helicase loading from helicase activation and replisome assembly. Using an in vitro assay for eukaryotic origin-dependent replication initiation, we investigated the control of these events. After helicase loading, we found that the Dbf4-dependent Cdc7 kinase (DDK) initially drives origin recruitment of Sld3 and the Cdc45 helicase-activating protein. more...

(Submitter supplied) Restricting the localization of the centromeric histone H3 variant CENP-A to centromeres is essential to prevent chromosomal instability (CIN). Mislocalization of overexpressed CENP-A contributes to CIN in yeast, fly, and human cells. CENP-A is overexpressed in many cancers. Therefore, defining mechanisms that prevent CENP-A mislocalization will help us understand how CENP-A overexpression contributes to CIN in cancer. more...

(Submitter supplied) DNA duplication is intimately connected to setting up post-replicative chromosome structures and events, but molecular details of this coordination are not well understood. A striking example occurs during yeast meiosis, where replication locally influences timing of the DNA double-strand breaks (DSBs) that initiate recombination. We show here that replication-DSB coordination is eliminated by overexpressing Dbf4-dependent Cdc7 kinase (DDK) or removing Tof1 or Csm3, components of the replication fork protection complex (FPC). more...

(Submitter supplied) In eukaryotes, CDC7 kinase is crucial for DNA replication initiation and has been involved in fork processing and replication stress response. Human CDC7 requires the binding of either one of two regulatory subunits, DBF4 and DRF1, for its activity. However, it is unclear whether the two regulatory subunits target CDC7 to a specific set of substrates, thus having different biological functions, or if they act redundantly. more...

(Submitter supplied) Similar to ubiquitin, SUMO forms chains, but the identity of SUMO-chain-modified factors and the purpose of this modification remain largely unknown. Here, we identify budding yeast SUMO protease Ulp2, able to disassemble SUMO chains, as a DDK interactor enriched at replication origins that promotes DNA replication initiation. Replication-engaged DDK is SUMOylated on chromatin, becoming a degradation-prone substrate when Ulp2 no longer protects it against SUMO-chain assembly. more...

(Submitter supplied) The replication of eukaryotic genomes is highly regulated to ensure faithful transmission of all genetic information through cell divisions. In addition to stringent control of origin initiation by cell cycle controls and DNA damage checkpoints, spatial and temporal control of origins serves to stage and balance replication of different genomic regions, with potential implications for development and genome stability. more...

(Submitter supplied) The occupancy states of DNA-binding nucleosomes and subnucleosome-sized proteins (e.g.  transcription factors, replication proteins, etc.) determine the chromatin accessibility landscape and provide additional regulatory context for DNA-templated processes including transcription and DNA replication. Throughout the mitotic cell division cycles, the transcriptome undergoes periodic reprogramming along with replication- and mitosis-induced global chromatin reconfiguration; however, profiling of the cell cycle-specific chromatin dynamics and understandings of its regulatory mechanisms remain limited. more...

(Submitter supplied) Across eukaryotes, checkpoints maintain the order of cell cycle events in the face of DNA damage or incomplete replication. Although a wide array of DNA lesions activates the checkpoint kinases, whether and how this response differs in different phases of the cell cycle remains poorly understood. The S-phase checkpoint for example results in the slowing of replication, which in the budding yeast Saccharomyces cerevisiae is caused by Rad53 kinase-dependent inhibition of the initiation factors Sld3 and Dbf4. more...

(Submitter supplied) Eukaryotic genomes are replicated in spatiotemporal patterns that are stereotypical for individual genomes and developmental profiles. In the model system S. cerevisiae, two primary mechanisms determine the preferential activation of replication origins during early S phase, thereby largely defining the consequent replication profiles of these cells. Both mechanisms are thought to act through specific recruitment of a rate-limiting initiation factor, Dbf4-dependent kinase (DDK), to a subset of licensed replication origins. more...

(Submitter supplied) Faithful DNA replication is essential for normal cell division and differentiation. In eukaryotic cells, DNA replication takes place on chromatin. This poses the critical question as to how DNA replication can progress through chromatin, which is inhibitory to all DNA-dependent processes. Here, we have developed a novel genome-wide method to measure chromatin accessibility to micrococcal nuclease that is normalized for nucleosome density, NCAM (Normalized Chromatin Accessibility to MNase) assay. more...

(Submitter supplied) 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 is bound in G1" might be considered to provide an operational definition of a replication origin. more...

(Submitter supplied) During routine genome duplication, many potential replication origins remain inactive, or 'dormant'. Such origin dormancy is achieved, in part, by an interaction with the metabolic sensor SIRT1 deacetylase. We report here that dormant origins are a group of consistent, pre-determined genomic sequences that can be distinguished from baseline (i.e. ordinarily active) origins by their preferential association with MCM2, a component of the replicative helicase, phosphorylated on serine 108 (pS108-MCM2). more...

(Submitter supplied) Forkhead box (FOX) transcription factors regulate a wide variety of cellular functions in higher eukaryotes, including cell cycle control and developmental regulation. In Saccharomyces cerevisiae, Forkhead proteins Fkh1 and Fkh2 perform analogous functions, regulating genes involved in cell cycle control, while also regulating matingtype silencing and switching involved in gamete development. Recently, we revealed a novel role for Fkh1 and Fkh2 in the regulation of replication origin initiation timing, which, like donor preference in mating-type switching, appears to involve long-range chromosomal interactions, suggesting roles for Fkh1 and Fkh2 in chromatin architecture and organization. more...
