It is generally considered that TNBC is an estrogen-independent breast cancer, while a new estrogen receptor , namely G protein-coupled estrogen receptor (GPER), is demonstrated to mediate estrogenic actions in

Orthosteric ligands preempt  natural signaling; they “take over” receptor behavior, forcing physiology Allosterics , in contrast, act more like tuning knobs—modulating receptor ensembles in partnership with The Dynamic Nature of Receptor Binding Forget the static “lock-and-key” metaphor. Ligands bounce in and out of receptor sites, competing dynamically. By stabilizing certain receptor states over others, ligands literally remodel the energy landscape.
