TGF-β can antagonise or cooperate with WNT signalling, yet it is still unclear what mechanisms integrate the outcomes of these conserved pathways. A new study now reports that the formation of biomolecular condensates, dependent on the DACT1 protein, provides the spatial segregation needed for TGF-β to constrain WNT signalling.
