Structural and evolutionary insights into DAF-12 interactions with transcriptional coactivators in parasitic nematodes

This study elucidates the structural and evolutionary mechanisms of DAF-12 coactivator recruitment in parasitic nematodes through multi-disciplinary approaches, revealing both conserved features shared with mammalian receptors and parasite-specific interactions that offer a new framework for developing antiparasitic therapies targeting this critical developmental switch.

Interdependent RNA structural motifs at the 3'-terminus of the West Nile virus genome regulate viral growth

This study reveals that four interdependent pseudoknots at the 3'-terminus of the West Nile virus genome function synergistically to regulate viral growth and sfRNA formation, with SLIV playing the dominant role, and identifies conserved tertiary motifs within this assembly as potential targets for pan-flaviviral therapeutics.

Mechanistic dissection of a dopamine-gated cation channel from Daphnia reveals key determinants of ligand selectivity and sensitivity

This study elucidates the molecular determinants of ligand selectivity and sensitivity in the *Daphnia magna* dopamine-gated cation channel (Dm-DopC1) by identifying specific mutations in binding loops that govern catecholamine responsiveness and reveal the receptor's hybrid pharmacological profile, thereby providing insights into the evolutionary flexibility of pentameric ligand-gated ion channels.

Filament Formation by ChlI Challenges the Current View of Magnesium Chelatase Architecture

Using cryo-electron microscopy, this study reveals that the ATPase subunit ChlI of magnesium chelatase forms ATP-dependent helical filaments that undergo compaction and partial Mg2+ dehydration upon hydrolysis, creating a specific conformation required for ChlD engagement and modulated by membrane lipids.

Breast cancer metabolism and responsiveness to dichloroacetate: relationships with 15N and 13C natural abundance

This study demonstrates that natural isotope abundance ({delta}{superscript 1}3C and {delta}{superscript 1}N) reflects distinct metabolic reprogramming and differential responsiveness to dichloroacetate treatment in breast cancer models, suggesting that lipid-derived {delta}{superscript 1}N could serve as a noninvasive biomarker for tumor metabolic state.

Structural insights into the inactive state of the adhesion GPCR ADGRV1

This study presents the first high-resolution cryo-EM structure of the inactive adhesion GPCR ADGRV1, revealing that its unique structural features, including a divergent tethered agonist and a closed intracellular loop 3, enable weak constitutive Gi signaling through an activation mechanism distinct from the canonical tethered agonist model.

Nar1 binds the cytosolic iron sulfur cluster assembly targeting complex via a bipartite interaction interface

This study elucidates the molecular mechanism of Nar1 recruitment to the cytosolic iron-sulfur cluster assembly targeting complex (CTC), revealing that a bipartite interaction involving both a primary electrostatic anchor on Cia1 and a secondary peptide binding at the Cia1-Cia2 interface positions Nar1 for efficient Fe-S cluster transfer.
