Abstract

We unraveled that the transactivation domain of estrogen receptor is structurally disordered, yet unexpectedly compact, and that a metastable Ile33-Ser118 contact is observed to inhibit coactivator binding. Disruption by mutagenesis alters ensemble-structures and coactivator binding, providing a functional link of oncogenic Ser118 phosphorylation in breast cancer endocrine resistance.
