Activation of the estrogen receptor-a (ER-α).
Ribbon diagram shows ER-α
(yellow) bound to a peptide of the Grip1 coactivator (red) and to the ER-α
agonist tetrahydrocrysene (blue). ER-α has
well-known roles in the progression and treatment of breast and uterine cancer,
whereas ER-β contributes
to resistance to prostate and colon cancer. This structure defines features that
are required for tetrahydrocrysene to act as an ER-α
agonist, but as an antagonist of ER-β,
and it reveals the mechanism of ligand-selective signaling. Work and image done
in the laboratory of Kendall W. Nettles, Ph.D.
