Their functionality relies on a dynamic proteome and precise spatiotemporal interactions with other organelles, making LD biology highly complex. Tools that enable the sequestration and release of LDs within their intracellular environment could synchronize their behavior, providing deeper insights into their functions. To address this need, we developed Controlled Trapping of LDs (ControLD), a new method for manipulating LD dynamics. This approach uses engineered condensates to reversibly sequester LDs, temporarily halting their activity. Upon release, the LDs resume their normal functions. ControLD effectively disrupts LD remobilization during metabolic demands and prevents the formation of LD–mitochondria contact sites, which are re-established upon condensate dissociation. ControLD represents a powerful tool for advancing the study of LD biology and opens avenues for investigating and manipulating other cellular organelles.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"80 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144103956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, enNlovFz2 efficiently mediated gene disruption in mouse embryos and restored dystrophin expression in a humanized Duchenne muscular dystrophy mouse model with single adeno-associated virus delivery.

Here we identified the nuclear E3 ligase ubiquitin protein ligase E3 component n-recognin 5 (UBR5) poly-ubiquitinated VGLL4 at Lys61 for its degradation, which permits Hippo–YAP signaling for the development of the liver biliary system in mice and multiple cancers in humans. In mouse liver development, Ubr5 and Vgll4 exhibited reciprocal expression patterns spatiotemporally. Ubr5 deletion impaired cholangiocyte development and hepatocyte reprogramming, which could be efficiently rescued by restoring Hippo–YAP through ablating Vgll4. We also found that the UBR5–VGLL4–YAP axis is associated with the progression of human pan-cancers. Targeting nuclear E3 ligases in multiple types of patient-derived tumor organoids suppressed their expansion. Our identification of UBR5 as the bona fide E3 ligase of VGLL4 offers a molecular framework of nuclear Hippo–YAP regulation and suggests nuclear ubiquitination as a potential therapeutic target for YAP-dependent malignancies.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"5 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adhesion G-protein-coupled receptors (aGPCRs), with large N termini, are ideal for allosteric modulator development. We designed a nanobody strategy targeting ADGRG2 N-terminal fragments and got a specific nanobody Nb23-bi, which promoted dehydroepiandrosterone (DHEA)-induced ADGRG2 activation and reversed mutant-induced dysfunctions. By combining structural characterization, crosslinking mass spectrometry, mutational analysis and molecular dynamics simulations, we clarified the allosteric mechanism of how the Nb23-bi modulates conformational changes in the DHEA-binding pocket. Animal studies showed that Nb23-bi promoted the response of DHEA in alleviating testicular inflammation and reversing mutant defects. In summary, we developed an allosteric nanobody of ADGRG2 and gained insights into its functions in reversing disease-associated dysfunctions.

Aberrant stress granule condensate formation is associated with disease, making it a potential target for pharmacological intervention. Here, we identified lipoamide, a small molecule that specifically prevents cytoplasmic condensation of stress granule proteins. Thermal proteome profiling showed that lipoamide stabilizes intrinsically disordered domain-containing proteins, including SRSF1 and SFPQ, which are stress granule proteins necessary for lipoamide activity. SFPQ has redox-state-specific condensate dissolving behavior, which is modulated by the redox-active lipoamide dithiolane ring. In animals, lipoamide ameliorates aging-associated aggregation of a stress granule reporter protein, improves neuronal morphology and recovers motor defects caused by amyotrophic lateral sclerosis-associated FUS and TDP-43 mutants. Thus, lipoamide is a well-tolerated small-molecule modulator of stress granule condensation, and dissection of its molecular mechanism identified a cellular pathway for redox regulation of stress granule formation.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"116 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyses of A. borkumensis mutants and expression studies reveal that the nonribosomal peptide synthetase catalyzes the synthesis of the aglycone (tetra-d-3-hydroxydecanoyl-glycine) from glycine and d-3-hydroxydecanoyl-CoA, to which a glucose moiety is added by the glycosyltransferase. Deficiency in glycine-glucolipid impairs the ability of mutant cells to attach to the oil–water interface, compromises growth on hexadecane and affects carbon storage. The glycine-glucolipid is essential for biofilm formation on oil droplets and uptake of alkanes. The high incidence of Alcanivorax at oil-polluted sites can in part be explained by the accumulation of the glycine-glucolipid on the cell surface, effectively making the cells themselves act as biosurfactants.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"141 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143926803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we uncover a nonribosomal peptide synthetase-independent biosynthetic pathway for E-64, which is widely conserved in fungi. The pathway starts with epoxidation of fumaric acid to the warhead (2S,3S)-trans-epoxysuccinic acid with an Fe(II)/α-ketoglutarate-dependent oxygenase, followed by successive condensation with an l-amino acid by an adenosine triphosphate grasp enzyme and with an amine by the fungal example of amide bond synthetase. Both amide bond-forming enzymes display notable biocatalytic potential, including scalability, stereoselectivity toward the warhead and broader substrate scopes in forming the amide bonds. Biocatalytic cascade with these amide bond-forming enzymes generated a library of cysteine protease inhibitors, leading to more potent cathepsin inhibitors. Additionally, one-pot reactions enabled the preparative synthesis of clinically relevant inhibitors.
