Notes

original target text: TEAD Inhibitor

TEAD refers to a family of transcription factors (TEAD1-4) that act as the final DNA-binding effectors of the Hippo signaling pathway, a conserved network that controls organ size, tissue regeneration, and cell proliferation. TEAD proteins themselves cannot activate gene expression alone; they require binding partners, principally the coactivators YAP and TAZ, to switch on genes that drive cell growth and survival. In healthy tissue, the Hippo pathway keeps YAP and TAZ inactive by promoting their phosphorylation and cytoplasmic retention, limiting TEAD-driven transcription. In several cancers, mutations or losses in upstream Hippo pathway components (such as the tumor suppressor NF2) release this restraint, allowing YAP/TAZ to accumulate in the nucleus and continuously engage TEAD, producing unchecked proliferative signaling. Small molecules that inhibit TEAD, typically by occupying a lipid-binding pocket required for its activity or by blocking its interaction surface with YAP/TAZ, aim to interrupt this transcriptional output directly at the point where multiple upstream lesions converge. This makes TEAD inhibition a mechanistically attractive strategy for cancers driven by Hippo pathway dysregulation, including tumors with NF2 loss, where few other targeted approaches address the underlying signaling defect.
