This study utilizes AlphaFold2 predictions and experimental validation to identify a distinct clade of constitutively active, monomorphic RfaH homologs associated with virulence operons, thereby supporting a stepwise evolutionary model where RfaH specialized from an active NusG-like ancestor into an autoinhibited fold-switching regulator.
This paper introduces Peptergent, a novel class of amphipathic peptides that enable the detergent-free extraction and purification of membrane proteins into stable, water-soluble assemblies, thereby overcoming traditional detergent limitations and facilitating direct structural and mass spectrometry analysis for improved proteomic coverage and drug screening.
The paper introduces FLEX, a compact, engineered fusion tag derived from fibroblast growth factor 1 that significantly enhances the expression, solubility, and high-stringency purification of challenging recombinant proteins across both bacterial and mammalian systems.
This study reveals that UFMylation of the pyruvate dehydrogenase subunit DLAT at lysine 118 activates mitochondrial metabolism by enhancing pyruvate oxidation, a process normally regulated by the de-UFMylase UFSP2.
This study demonstrates that seed extracts from seven economically important Korean forest tree species exhibit diverse, species-specific antioxidant, anti-inflammatory, whitening, and anticancer activities, highlighting their potential as sustainable multifunctional bioresources derived from existing afforestation programs.
This study establishes a CRISPR/Cas9-generated PCSK9 knockout HepG2 cell line as a rigorous high-resolution platform for quantitatively assessing the functional impact of clinically relevant PCSK9 variants on LDL uptake, revealing significant phenotypic heterogeneity and providing a mechanistic framework to bridge genetic discovery with precision lipid-lowering strategies.
This study elucidates the structural mechanism by which UFD1 engages initiator and proximal ubiquitins to drive p97-mediated substrate unfolding and reveals how accessory adaptors FAF1, FAF2, and UBXD7 enhance this process through distinct scaffolding and stabilization strategies.
This study maps the TRiC/CCT chaperonin interactome in mouse rod photoreceptors to reveal that TRiC dysfunction triggers a metabolic energy crisis and proteostasis imbalance, ultimately driving neurodegeneration through disrupted glucose uptake and substrate overload.
This study demonstrates that cadaveric fly larvae serve as a rich ecological reservoir for diverse *Streptomyces* species, which were found to produce a wide array of bioactive natural products, including potent anthelmintic compounds like JBIR-68 and Simamycin, thereby highlighting this overlooked system as a promising source for novel biomedical discoveries.
This study reveals that the adaptor protein SDC-3 recruits the condensin IDC complex to *C. elegans* X chromosomes by binding to the DPY-27 subunit to relieve auto-inhibition, thereby enabling loop-extrusion activity that drives chromosome-wide transcriptional repression for dosage compensation.
