Molecular Architecture of Cryptococcus Cell Walls Reveals Species-Specific Chitosan-Dependent Remodeling

This study utilizes solid-state NMR to demonstrate that chitosan is essential for maintaining the structural integrity and hydration of *Cryptococcus* cell walls, with its absence triggering distinct, species-specific remodeling of the polysaccharide network that differentially impacts *C. neoformans* and *C. gattii*.

Ankur, A., Upadhya, R., Doosti, M., Ferreira, D., Xie, L., Hung, I., Lodge, J., Wang, T.2026-04-15⚗️ biochemistry

Small Molecule Regulation of CLOCK:BMAL1 DNA Binding Activity

This study demonstrates that small molecules binding to a cavity within the CLOCK PAS-A domain stabilize the protein and induce dose-dependent displacement of the CLOCK:BMAL1 complex from DNA, thereby revealing a mechanism for regulating circadian transcription factor activity through ligand occupancy.

Sharma, D., Boral, S., West, E., Kressman, M., Franco, I., Amezcua, C. A., Tripathi, S., Lee, H.-W., Favaro, D. C., Gardner, K. H., Partch, C. L.2026-04-14⚗️ biochemistry

Crystal structure and molecular dynamics simulations of rademikibart Fab-IL-4Rα complex reveal biochemical basis for next-generation potent IL-4Rα inhibition in type 2 allergic and inflammatory diseases

This study elucidates the structural and dynamic mechanisms underlying rademikibart's superior potency as a second-generation IL-4Rα inhibitor compared to dupilumab, revealing that its unique binding orientation and specific interactions with the receptor's third interface loop enable more effective blockade of cytokine signaling.

Beyond the surface: plasmalogens are dispensable for retinal integrity and fertility in the mouse

This study demonstrates that in mice, plasmanyl lipids are sufficient to prevent cataracts and maintain fertility, indicating that plasmalogens are dispensable for retinal integrity and reproductive function despite their critical role in total ether lipid deficiency.

Dorigatti, I., Juric, V., Blumer, M. J., Kummer, D., Kokot, J., Golderer, G., Dorninger, F., Berger, J., Keller, M. A., Watschinger, K.2026-04-12⚗️ biochemistry

Proteomics-Based Discovery of Symmetry-Specific Readers and Antireaders of 5-Formylcytosine in Mammalian DNA

This study presents the first proteome-wide analysis revealing that mammalian proteins, including transcription factors and DNA repair enzymes, exhibit diverse and symmetry-specific recognition patterns for 5-formylcytosine modifications in CpG dyads, thereby modulating target selection and chromatin regulation.
