Description
Using an estrogen response element (ERE)-luciferase reporter system co-transfected with one of five ESR1 mutants, the N538G ligand binding domain mutation was shown to result in constitutive activity (response in the absence of beta-estradiol ligand) and continued responsiveness (inhibition of downstream target activation) to anti-estrogen therapies (tamoxifen or fulvestrant) in HEK293T cell lines.
