This paper introduces an interleaved multi-magnification cryo-electron tomography strategy that simultaneously captures large-scale cellular organization and high-resolution molecular structures within the same tilt series, effectively bridging the gap between cellular and structural biology.
This study reveals that the eukaryotic COMMD protein family, essential for membrane trafficking, originated from an ancestral bacterial gene found in Myxococcota, which evolved through multiple duplications into a heterodecameric ring structure that retains the homomeric ring-forming capabilities of its prokaryotic predecessors.
By integrating circulating proteomic data with diverse machine learning algorithms, this study identifies a panel of discriminative biomarkers and reveals significant molecular heterogeneity within obesity and type 2 diabetes, offering a framework for improved disease stratification.
The study demonstrates that a full-atom MPNN-based design framework (FAMPNN) successfully engineered thermostable variants of the plant dehydrogenase SrBDH1 with up to 10°C enhanced stability and extended half-life, while fully preserving its stereoselectivity for (+)-borneol.
This study utilizes a high-density genomic SNAP DNA-binding array to comprehensively define the sequence specificity, dimeric binding mechanics, and flanking sequence influences of the transcription factor GRHL2, thereby distinguishing its direct DNA occupancy from indirect cofactor-mediated recruitment.
By integrating bulk and single-cell transcriptomic analyses, this study identifies seven vascular aging-related hub genes (including TNF, MMP9, and APOE) as key diagnostic biomarkers and immune drivers in atherosclerosis, while proposing curcumin as a potential therapeutic agent targeting these genes.
This study reveals that the accumulation of native entanglement misfolding in globular proteins is a key driver of age-associated structural changes across the *Saccharomyces cerevisiae* proteome, as these entangled regions are significantly more prone to forming long-lived, near-native misfolded states during aging.
This study demonstrates that phosphorylation of the intrinsically disordered N-terminal motif A in SIRT1, particularly at Ser27, induces structural folding into an ordered conformation that significantly enhances the enzyme's deacetylase activity.
This paper proposes a revised theoretical framework that expands the classification boundaries of cephalopod reflectin proteins to accommodate newly discovered sequence diversity across ten species, enabling more accurate identification and deeper structural-functional analysis of these dynamic optical systems.
This study identifies a novel stress-response pathway in *Mycobacterium tuberculosis* where the enzyme Rv1722 synthesizes the metabolite GABA-trehalose from accumulated GABA and trehalose under hypoxic and nitric oxide stress, representing a previously unknown metabolic adaptation to immune-imposed conditions.
