Although the replication, expression, and maintenance of DNA are well-studied processes, the way that they are coordinated is poorly understood. Here, we report an analysis of the changing association of proteins with chromatin (the chromatin proteome) during progression through interphase of the cell cycle. Sperm nuclei were incubated in Xenopus egg extracts, and chromatin-associated proteins were analyzed by mass spectrometry at different times. Approximately 75% of the proteins varied in abundance on chromatin by more than 15%, suggesting that the chromatin proteome is highly dynamic. Proteins were then assigned to one of 12 different clusters on the basis of their pattern of chromatin association. Each cluster contained functional groups of proteins involved in different nuclear processes related to progression through interphase. We also blocked DNA replication by inhibiting either replication licensing or S phase CDK activity. This revealed an unexpectedly broad system-wide effect on the chromatin proteome, indicating that the response to replication inhibition extends to many other functional modules in addition to the replication machinery. Several proteins that respond to replication inhibition (including nuclear pore proteins) coprecipitated with the Mcm2-7 licensing complex on chromatin, suggesting that Mcm2-7 play a central role in coordinating nuclear structure with DNA replication.

The role of DDK and Treslin-MTBP in coordinating replication licensing and pre-initiation complex formation

Ilaria Volpi, Peter J. Gillespie, Gaganmeet Singh Chadha, J. Julian Blow

Summary: Treslin/Ticrr is essential for DNA replication initiation and forms a complex with MTBP. DDK and CDK activities cooperate to regulate the interaction of Treslin-MTBP, which is crucial for selecting replication origins. This study provides insights into the mechanisms behind replication initiation regulation.

DDK: The Outsourced Kinase of Chromosome Maintenance

Peter J. Gillespie, J. Julian Blow

Summary: To ensure genetic stability, cells must duplicate their complement of chromosomes prior to cell division. This process involves replicating chromosomal DNA and re-establishing the chromatin environment. The duplication of chromatid pairs must remain coupled until cell division to ensure equal segregation of genetic material. Cyclin-dependent kinases (CDK) control the regulation of chromosome duplication. CDK also activates Dbf4-dependent kinase (DDK), which facilitates DNA replication activation and coordination with chromatin re-establishment and chromatid coupling. This review discusses the outsourcing of these activities by CDK to DDK to ensure chromosome maintenance during cell division.

Summary: The RNA-binding ARS2 protein is involved in both early RNA polymerase II (RNAPII) transcription termination and transcript decay. It binds to ZC3H4 to recruit it to chromatin for RNAPII termination and forms a direct connection to the NEXT complex for rapid degradation of the RNA. ARS2 functions differently at CPA-instructed termination sites.

The IFT81-IFT74 complex acts as an unconventional RabL2 GTPase-activating protein during intraflagellar transport

Summary: Cilia are important cellular organelles for signaling and motility and are constructed via intraflagellar transport (IFT). RabL2 localizes to the basal body of cilia via an interaction with CEP19 before downstream association with the IFT machinery. Reconstituted pentameric IFT complex containing IFT81/74 enhances the GTP hydrolysis rate of RabL2. Structural models of RabL2-containing IFT complexes validate the architectural understanding of RabL2 incorporation into the IFT complex.

Dual agonistic and antagonistic roles of ZC3H18 provide for co-activation of distinct nuclear RNA decay pathways

Patrik Polak, William Garland, Om Rathore, Manfred Schmid, Anna Salerno-Kochan, Lis Jakobsen, Maria Gockert, Piotr Gerlach, Toomas Silla, Jens S. Andersen, Elena Conti, Torben Heick Jensen

Summary: The RNA exosome is a versatile ribonuclease that functions in the nucleoplasm of mammalian cells. It is assisted by the nuclear exosome targeting (NEXT) complex and the poly(A) exosome targeting (PAXT) connection. The PAXT pathway targets short adenylated RNAs through the ZFC3H1 component, which interacts directly with ARS2. In addition, ZC3H18 competes with PAXT and antagonizes its activity.
