This study elucidates the full-length in-cell secondary structure of the breast cancer-associated lncRNA HOTAIR, revealing its multidomain architecture, context-specific structural features, and evolutionary conservation to provide a structural roadmap for understanding its role in gene regulation and metastasis.
This study demonstrates that catechinopyranocyanidins derived from adzuki beans exhibit potent antioxidant activity primarily driven by a hydrogen atom transfer mechanism and provide cytoprotective effects against mitochondrial dysfunction-induced cell death in human dermal fibroblasts.
This study employs APEX2-based dual proximity labeling coupled with data-independent acquisition mass spectrometry to comprehensively map the interactome of human TRMT1, revealing its association with RNA processing, tRNA biogenesis, and redox stress response pathways.
This study demonstrates that B3GNT7 is a critical regulator of colonic mucin O-glycosylation that maintains mucus integrity and protects against colitis and enteric infection.
This study elucidates how high enantioselectivity in borneol dehydrogenases evolved through a combination of a single active-site mutation (I111L) and peripheral mutations that modulate the hydrophobic pocket's solvent-accessible surface area, offering a blueprint for rational protein engineering.
This study reveals that the Rev1 scaffold protein exerts opposing regulatory control over DNA polymerase zeta by stimulating its activity on damaged DNA while inhibiting it on undamaged DNA through an evolutionary conserved N-terminal M1 motif, a mechanism that requires a stable Rev1-Pol zeta complex coordinated by PCNA and is critical for preventing complex mutations without altering overall spontaneous mutation rates.
This study utilizes cryo-EM to reveal the structural mechanism of CMGE biogenesis during pre-Initiation Complex assembly, demonstrating how Sld2 facilitates GINS recruitment, CMGE dimer separation, and lagging strand ejection to establish bidirectional replication forks.
By integrating symmetry analysis with ancestral sequence reconstruction, this study elucidates the evolutionary origin of the ZIP metal transporter fold, reveals a symmetric translocation pathway with defined gating mechanisms, and identifies specific residues that govern metal transport and subfamily functional specialization.
This study reveals that the C-terminal α-helix of the lipid carrier MlaC acts as a conformational switch in *Pseudomonas aeruginosa*, regulating its interaction with the MlaD hexamer and controlling phospholipid cavity accessibility to facilitate lipid transport.
This study reveals that the essential DNA repair enzyme APE1 achieves high catalytic efficiency through a novel "moving metal ion" mechanism, where orchestrated Mg2+ repositioning and a distal hydrogen-bonding network enable concerted catalysis without a pentavalent intermediate, offering new insights for designing cancer inhibitors.
