TEAD transcription factors regulate gene expression through interactions with DNA and other proteins. They are crucial for the development of eukaryotic organisms and to control the expression of genes involved mostly in cell proliferation and differentiation, however, their deregulation can lead to tumorigenesis. To study the interactions of TEAD1 with M-CAT motifs and their inverted versions, the K-D of each complex was determined, and H/D exchange, quantitative chemical cross-linking, molecular docking, and smFRET were utilized for structural characterization. ChIP-qPCR was employed to correlate the results with a cell line model. The results obtained showed that although the inverted motif has 103higher K-D, the same residues were affected by the presence of M-CAT in both orientations. Molecular docking and smFRET revealed that TEAD1 binds the inverted motif rotated 180 degrees. In addition, the inverted motif was proven to be occupied by TEAD1 in Jurkat cells, suggesting that the low-affinity binding sites present in the human genome may possess biological relevance.
