TEAD

TEAD (TEA domain) transcription factors comprise a highly conserved family of DNA-binding proteins that function as the major transcriptional effectors of the Hippo signaling pathway and regulate cell growth, proliferation, tissue homeostasis, regeneration, and embryonic development^[1][2]. Mechanistically, TEAD proteins bind genomic target sequences and cooperate with the transcriptional coactivators YAP and TAZ to control transcriptional programs that govern cellular proliferation, differentiation, and survival^[1][3]. Through this YAP/TAZ-TEAD transcriptional module, Hippo pathway activity is translated into gene-expression outputs that influence developmental processes and organ homeostasis^[1][4]. In disease contexts, increased TEAD transcriptional activity has been associated with tumorigenesis and therapeutic resistance, and dysregulated Hippo signaling can promote TEAD-dependent oncogenic transcription in multiple cancer types^[3][5][6]. Experimental studies further demonstrate that disruption of YAP-TEAD interactions suppresses YAP-dependent gene expression and oncogenic transformation, supporting TEAD as a critical functional node in cancer biology^[3]. Compared with related family members, TEAD1, TEAD3, and TEAD4 are broadly expressed in multiple adult tissues, whereas TEAD2 displays a more restricted embryonic expression pattern and is largely absent from adult tissues, indicating distinct biological roles despite strong structural conservation^[7]. Research on TEAD-targeted therapeutics has therefore focused on inhibitors that disrupt TEAD-mediated transcriptional complexes or directly antagonize TEAD activity, providing valuable experimental tools for investigating Hippo pathway function and evaluating anticancer strategies^[5][8][9].
