This study reveals that in anti-MDA5 dermatomyositis, autoantibodies bind to LINE RNA-scaffolded MDA5 filaments to form pathogenic extracellular immune complexes that drive a self-amplifying inflammatory cycle through higher-order aggregation and potent innate immune activation.
This study reveals that N-terminal pyroglutamylation enables subtype-selective GPCR activation through a "distal steering" mechanism where the rigid modification reshapes the ligand's conformational ensemble to differentially engage receptor pockets without direct contact, a principle demonstrated across both Aplysia PRXamide and human Neuromedin U signaling systems.
This study employs genetic code expansion to introduce a photo-crosslinkable unnatural amino acid into the yeast 26S proteasome, enabling the in vivo capture and mass spectrometry identification of diverse, ATP-dependent protein substrates and revealing how their landscape shifts under endoplasmic reticulum stress.
This paper presents a novel protocol that overcomes the challenges of isolating rare neuronal lipid droplets by blocking triglyceride lipase to enlarge them for sucrose gradient purification, enabling detailed lipidomic profiling to advance the understanding of their role in neurodegenerative disorders.
This study reports the successful isolation and in vitro reconstitution of the cobalamin-dependent radical SAM enzyme BchE, enabling the first detailed characterization of its catalytic mechanism in the anaerobic biosynthesis of bacteriochlorophyll.
UniFlow is a scalable normalizing flow framework that unifies protein conformational ensemble generation and machine-learned coarse-grained force fields, enabling both rapid sampling of equilibrium distributions and stable long-timescale molecular dynamics simulations within a single differentiable model.
This study utilizes activity-based protein profiling with fluorophosphonate probes to generate a comprehensive chemoproteomic map of the *Trypanosoma cruzi* serinome, identifying 37 active serine hydrolases involved in lipid metabolism and host-pathogen interactions to facilitate future antiparasitic drug discovery.
This study reveals that the detachable tailspike protein TspA of *Rhodobacter capsulatus* gene transfer agents functions as a potent biofilm-degrading enzyme that facilitates horizontal gene transfer by enabling navigation through complex microbial extracellular matrices.
This study reveals that the limited genome-editing activity of TnpB stems from inefficient DNA unwinding into a stable open state, and demonstrates that an optimized variant (Ymu1-WFR) enhances both in vitro cleavage and plant genome editing by stabilizing specific unwinding intermediates.
This study demonstrates that the molecular glue degrader EM12-FS covalently remodels cereblon (CRBN) at His353 to create a novel, non-canonical interface that enables the selective recruitment and degradation of the neosubstrate NTAQ1, thereby expanding the scope of induced-proximity pharmacology through site-specific synthetic modification.
