Discovery of the day
This study identifies Homer proteins as condensate-forming effectors that transduce polarity signals from the Crumbs complex to regulate YAP and Wnt transcriptional pathways. The researchers demonstrate that Homer scaffolds assemble into phase-separated condensates at cell junctions, coordinating a signaling crosstalk that controls tissue growth and organ size. For your research interests in cellular disruptions and tissue homeostasis, these findings reveal a novel molecular mechanism linking cell polarity to transcriptional programs, with potential implications for understanding how polarity aberrations contribute to developmental programming defects and age-related tissue dysfunction, including those affecting reproductive tissues.
