Whereas activation of STATs by JAKs via canonical receptor-driven JAK-STAT signaling is well understood, little is known about JAK-independent mechanisms of STAT activation. Here, we identify the understudied nonreceptor tyrosine kinase TNK1 as a therapeutically targetable, JAK-independent activator of STAT signaling. Using a multiomics approach, we mapped a network of TNK1 substrates associated with protein condensates and proinflammatory signaling, including STAT1. We found that TNK1, but not its sister kinase ACK1, directly phosphorylates STATs at well described STAT-activating JAK sites. In cells, TNK1-mediated STAT1 phosphorylation and activation occurs independently of JAKs. Imaging and interactomics data suggest that TNK1 interacts with STAT1 in cytosolic condensates, which likely compartmentalize TNK1-substrate interactions. We show that an intrinsically disordered proline-rich region in TNK1, which includes a 14-3-3 docking phosphorylation site, is required for the formation of kinase-active TNK1 condensates and STAT1 phosphorylation. Mutations within the proline-rich region that eliminate 14-3-3 binding increase formation of TNK1 condensates, suggesting a model in which 14-3-3 acts as a clamp that constrains the flexible PRR to inhibit condensate formation and STAT1 activation.

Despite substantial progress in defining these structural features, whether 3D genome architecture plays a causal role in regulating processes such as transcription, DNA replication, and DNA repair, or instead reflects underlying regulatory activity, remains unresolved. Here, we use the distinction between chromatin-intrinsic features and architectural factors as a framework to evaluate evidence for causality in genome structure-function relationships. We extend this framework to cancer, where both intrinsic alterations (including noncoding mutations, structural variants, and changes in chromatin state) and architectural factor perturbations (such as mutations in architectural proteins and dysregulation of transcriptional machinery) disrupt genome organization and contribute to disease progression. These findings suggest that alterations in genome structure can, in some contexts, actively reshape oncogenic programs. A major limitation in applying 3D genome insights to cancer biology is the cost and complexity of omics assays. Recent advances in artificial intelligence (AI) and machine learning (ML) enable inference and prediction of 3D genome organization from sequence and epigenomic features, providing insight into the extent to which genome folding is encoded intrinsically versus dynamically regulated in architectural factors.

However, upstream mechanisms regulating this pathway remain incompletely defined. Here, we apply CRASP-seq, a scalable RNA-coupled CRISPR screening platform, to systematically identify regulators of XBP1 splicing. We uncovered the U2 snRNP auxiliary factor RBM39 as a critical positive regulator of this process. Perturbation of RBM39 or U2 snRNP components induces alternative splicing of <i>ERN1</i>, leading to exon-18 skipping and the production of an unstable transcript subject to nonsense-mediated decay, as well as a truncated IRE1α isoform that acts in a dominant-negative manner to suppress XBP1 splicing. Mechanistically, we show that heat shock reduces RBM39 functional activity and promotes <i>ERN1</i> exon-18 skipping, thereby attenuating IRE1α-XBP1 signaling. Functionally, hyperactivation of this pathway is detrimental under proteotoxic stress, suggesting that exon-18 skipping serves as a stress-adaptive mechanism to limit UPR output. Together, our findings reveal a previously unrecognized regulatory axis linking the canonical splicing machinery to UPR signaling and establish alternative splicing of <i>ERN1</i> as a key modulator of cellular stress responses.</p>","PeriodicalId":12591,"journal":{"name":"Genes & development","volume":" ","pages":"1448-1465"},"PeriodicalIF":7.4,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13532665/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148689043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
