VGLL4, which occupies TEAD to prevent YAP binding, is the main transcriptional repressor of Hippo–YAP activity. 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.</p><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}

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.</p><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}
