Abstract excerpt
Thyroid hormone action is mediated by thyroid hormone receptors (TRs), which are members of the nuclear hormone receptor superfamily. DNA-binding is presumed to be essential for all nuclear actions of thyroid hormone. To test this hypothesis in vivo, the DNA-binding domain of TR-beta was mutated within its P-box (GS mutant) using gene targeting techniques. This mutation in vitro completely abolishes TR-beta...
