agonist An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the ag ...

transactivation In the context of gene regulation: transactivation is the increased rate of gene expression triggered either by biological processes or by artificial means, through the expression of an intermediate transactivator protein. In the context of recep ...

for the ERβ over the ERα. Its affinity for the ERβ was 3.43 μM and for the ERα was 22.5 μM, while it activated the ERβ and ERα with EC₅₀ values of 1.71–2.5 μM and 19.8–22.5 μM, respectively. As such, its binding selectivity for the ERβ over the ERα was 7-fold and its

functional selectivity Functional selectivity (or “agonist trafficking”, “biased agonism”, “biased signaling”, "ligand bias" and “differential engagement”) is the ligand-dependent selectivity for certain signal transduction pathways relative to a referen ...
