    Sld3CBD–Cdc45 structural insights into Cdc45 recruitment for CMG complex formation during DNA replication

    Hao Li, Izumi Ishizaki ... Min Yao
    The crystal structure of Sld3CBD-Cdc45 shows its intermolecular interactions, and subsequent Sld3CBD-CMG model construction and binding assays enable a proposal for the mechanism of Cdc45 recruitment and Sld3 release.

    The Mycobacterium tuberculosis complex pangenome is small and shaped by sub-lineage-specific regions of difference

    Mahboobeh Behruznia, Maximillian Marin ... Conor J Meehan
    The accessory genome of Mycobacterium tuberculosis is small, but differences in gene content are found both between and within lineages.

    Spatial integration of sensory input and motor output in Pseudomonas aeruginosa chemotaxis through colocalized distribution

    Zhengyu Wu, Maojin Tian ... Junhua Yuan
    In Pseudomonas aeruginosa, the chemoreceptor cluster and flagellar motor colocalize at the same cell pole through FlhF anchoring, preventing cross-pathway signaling interference between chemotaxis and c-di-GMP regulation.

    Newly discovered and conserved role of IgM against viral infection in an early vertebrate

    Weiguang Kong, Xinyou Wang ... Zhen Xu
    sIgM plays a role in viral neutralization across both primitive and modern vertebrates by following conserved principles in the development of specialized antiviral immunity.

    Deletion of sulfate transporter SUL1 extends yeast replicative lifespan via reduced PKA signaling instead of decreased sulfate uptake

    Juan Long, Meng Ma ... Jing Yang
    SUL1 deletion extends lifespan via PKA-MSN2 pathways, underscoring nutrient signaling over sulfate transport in aging regulation.

    DNA methylation insulates genic regions from CTCF loops near nuclear speckles

    Shelby A Roseman, Allison P Siegenfeld ... Brian B Liau
    CTCF binding promotes chromatin-nuclear speckle interactions and gene activation after DNA demethylation, yet its binding and looping patterns are unaffected by speckle depletion.

    WRN and WRNIP1 ATPases impose high fidelity on translesion synthesis by Y-family DNA polymerases

    Jung Hoon Yoon, Karthi Sellamuthu ... Satya Prakash
    WRN and WRNP1 ATPases together with WRN 3’ to 5’ exonuclease raise the fidelity of intrinsically highly error-prone Y-family DNA polymerases such that they perform error-free translesion synthesis.

    The Product neutrality function defining genetic interactions emerges from mechanistic models of cell growth

    Lucas Fuentes Valenzuela, Paul Francois, Jan M Skotheim
    Coarse-grained models of cellular growth and high-throughput empirical genetic data support the Product neutrality function in which a double-mutant fitness is the product of single-mutant fitnesses.

    Opening and closing of a cryptic pocket in VP35 toggles it between two different RNA-binding modes

    Upasana L Mallimadugula, Matthew A Cruz ... Gregory R Bowman
    The cryptic pocket is critical for one of the VP35 protein's functions and therefore is likely under selective pressure.

    Gene expression variation across genetically identical individuals predicts reproductive traits

    Amy K Webster, John H Willis ... Patrick C Phillips
    Differences among genetically identical individuals can be explained using expression levels of just a handful of genes, suggesting that environmental variation can be functionally analyzed.
