We reveal that TEADs are a major determinant of YAP DNA binding and nuclear mobility, while YAP minorly influences TEADs. YAP and TEAD1 associate with DNA for longer periods in cells with intrinsically low Hippo pathway activity and upon acute Hippo pathway perturbation. TEAD1 binds the genome on a broad range of timescales, and this is extended substantially in nuclear condensates.
