This study characterizes the functional mechanisms of *Schistosoma mansoni* STIM and ORAI proteins, demonstrating their conserved roles in calcium signaling while identifying specific structural and pharmacological differences from human orthologues that could be exploited for selective therapeutic targeting.
The study introduces NanoPilot, a modular fusion protein platform that competitively inhibits ApoE-mediated liver uptake of lipid nanoparticles to enable efficient, cell-specific extrahepatic delivery of genetic therapies.
This study reveals the cryo-EM structure of the *C. elegans* -tubulin ring complex, demonstrating how a unique 4-spoked subunit assembly replaces conserved components to template non-canonical 11-protofilament microtubules while retaining the capacity to form 13-fold symmetric structures in vitro.
This study demonstrates that the epigenetic inhibitor SP2509 can be converted into an optical timer of cell fate by exploiting its latent ortho-hydroxy acylhydrazone switch, which allows reversible light-controlled modulation of LSD1 activity to precisely regulate chromatin-dependent processes like senescence and apoptosis.
This paper presents a kinetics-based model that explains sequence-dependent DNA replication fidelity by combining nearest-neighbor stacking thermodynamics and directional kinetic asymmetry, successfully predicting experimental mutation spectra and revealing non-monotonic temperature dependence.
This study elucidates that human YRDC functions as a dimer where L-threonine acts as a gatekeeper ligand to stabilize the enzyme and enhance ATP binding, revealing that disease-causing mutations disrupt this dimerization and conformational stability to impair catalytic activity.
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.
