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.
This study characterizes FG214, a novel heme-binding one-component transcription factor from *Fimbriimonas ginsengisoli* that functions as a redox-regulated switch by transitioning from a monomer to a DNA-binding homodimer upon heme reduction, thereby offering a potential tool for biosensing and gene regulation.
This study reports the discovery of nitrilobacillins, a new class of ribosomally synthesized and post-translationally modified peptides (RiPPs) featuring unprecedented C-terminal nitrile groups generated by an asparagine synthetase-like enzyme, which function as cysteine protease inhibitors with warheads structurally similar to synthetic therapeutics like Paxlovid.
This study demonstrates that a modular -barrel domain swapping strategy applied to -hemolysin generates stable chimeric nanopores with tailored transport properties, significantly enhancing single-molecule sensing capabilities for nucleic acids and proteins.
This study utilizes pharmacological profiling and genomic editing to demonstrate that while DGK inhibitors like R59022 and BMS-502 exhibit paralog-specific effects on DGKalpha, effective reduction of phosphatidic acid levels during PLC signaling requires the simultaneous inhibition of both DGKalpha and phospholipase D enzymes.
This paper presents a solid-phase synthesis strategy for fluorogenic ProTide probes that enables ultrasensitive profiling of carboxypeptidase activities, revealing specific enzymatic signatures in human blood that distinguish pancreatic cancer patients from healthy controls.
Researchers discovered a novel dual thiobarbiturate-indole compound (MDOLL-0273) that selectively inhibits the chikungunya virus nsP3 macrodomain by binding to a cryptic pocket, offering a promising starting point for developing antiviral therapies against CHIKV.
