Figure 6From: Structural basis of GC-1 selectivity for thyroid hormone receptor isoformsBleicher6.png. Superposition of the crystal structures of T3 (blue and sky blue) and GC1 (red and orange) bound to two hTR isoforms highlights the conformational variability associated with the Ser277 and Asn331 residues. This variability is mostly a result of the lack of the amine group in GC-1, but its presence in T3.Back to article page
