摘要Hippo signaling is a highly conserved pathway central to diverse cellular processes.Dysregulation of this pathway not only leads to developmental abnormalities but is also closely related to the occurrence and progression of various cancers.Recent studies have uncovered that,in addition to the classical signaling cascade regulation,biomolecular condensates formed via phase separation play a key role in the spatiotemporal regulation of Hippo signaling.In this review,we provide a summary of the latest research progress on the regulation of the Hippo signaling pathway by phase separation,with a particular focus on transcriptional activation mediated by Yes-associated protein(YAP)ranscriptional coactivator with post-synaptic density-95,disks-large,and zonula occludens-1(PDZ)-binding domain(TAZ)condensates.Furthermore,we discuss the utility of chemical crosslinking combined with mass spectrometry to analyze the TAZ condensate interactome and examine the role of the protein fused in sarcoma(FUS)in modulating the biophysical properties of TAZ condensates,which in turn influence their transcriptional activity and pro-tumorigenic functions.These insights not only advance our understanding of Hippo signaling but also offer new perspectives for therapeutic interventions targeting diseases linked to dysregulated YAP/TAZ activity.
