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.
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.
sIgM plays a role in viral neutralization across both primitive and modern vertebrates by following conserved principles in the development of specialized antiviral immunity.

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 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.

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.

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.
