A substrate-biased activity-based probe technology was developed to enable relatively facile identification of proteases responsible for specific proteolytic events in complex biological milieu, revealing that urokinase regulates CDCP1 proteolysis.
A CRISPR–Cas9 screen combined with heparan sulfate (HS)-binding reagents identifies genes involved in HS biosynthesis and assembly and reveals the unexpected role of histone demethylase KDM2B in regulating HS presentation on the cell surface.
A dual-layer encapsulation approach provides physical containment of genetically modified bacteria (especially when combined with chemical containment) while also protecting them from environmental stressors and maintaining their sensing functions.
Combining the self-labeling HaloTag protein with synthetic environmentally sensitive fluorophores provides a platform for the construction of bright, far-red fluorescent calcium and voltage sensors with tunable photophysical and chemical properties.
Alterations in the interactions driving phase separation of the mRNA decapping complex led to conformational rearrangements in its active site, providing a mechanism to control whether substrate mRNA is stored or decapped in condensates.
Lysosome-targeting chimeras (LYTACs) based on glycan ligands of the asialoglycoprotein receptor facilitate the cell-specific targeting and turnover of proteins by lysosomal enzymes, expanding the scope of LYTAC-mediated targeted protein degradation.
CHYRON (Cell History Recording by Ordered Insertion) enables DNA recording of cellular states and lineage reconstruction by Cas9-targeted insertions of random nucleotides by terminal deoxynucleotidyl transferase.
The discovery of a specific CDK12 bivalent degrader, BSJ-4-116, reveals that chronic exposure of MOLT-4 and Jurkat cells to BSJ-4-116 leads to acquired resistance to the compound via point mutations in the CDK12 kinase domain.
A genome-wide screen discovers a naturally occurring ribozyme in humans termed hovlinc, which is embedded within a long noncoding RNA and has no apparent relation to known ribozymes.
Built of bacterial biofilm proteins, aquaplastic is a biodegradable material that can easily be processed from a hydrogel state into bulk materials, is resistant to acids, bases and organic solvents, and is easily healable and weldable in water.
A chemical screen identifies DHODH inhibitors as robust activators of mitochondrial respirasome assembly. Lipidomics reveal that peroxisomal-derived ether phospholipids accumulate in mitochondria during nucleotide deprivation to drive proliferation.
Acyl protein thioesterase APT2 interacts with membranes via its charged β-tongue, becomes palmitoylated by ZDHHC3/7 and deforms the bilayer to extract substrate acyl chains. APT2 deacylation leads to its membrane release and degradation.
TfuA, YcaO and thiol donor protein, ThiS, collaborate in peptide backbone thioamidation of McrA and during the biosynthesis of certain ribosomally synthesized and post-translationally modified peptide (RiPP) natural products.
Fusion of a split form of the protein O-GlcNAcase with nanobodies enables the targeted removal of O-GlcNAc protein modifications, providing a tool for probing the functional roles of specific O-GlcNAc modifications in a cellular context.
Kinetic modulatory profiling identifies regulators of ferroptosis, including the FDA-approved drug bazedoxifene, which acts in an off-target manner as a radical trapping antioxidant while mTOR inhibitors increased resistance to ferroptosis.
An agarose hydrogel mimicking cytoskeleton stabilizes protein liquid droplets and enables precise quantification of protein percentage in phase-separated droplets and in the dispersed phases as well as intramolecular distances via NMR and EPR.
The mutanofactin family of lipopeptide natural products, produced by strains of cariogenic Streptococcus mutans, promotes biofilm formation via increased cell-surface hydrophobicity and binding to extracellular DNA.
High mobility and nuclear translocation of the PKA catalytic subunit, PKAcat, relays signals induced by endosomal cAMP generated through endocytosis and signaling from the G-protein-coupled receptor β2-adrenergic receptor.
