Thyroid hormone receptor dimerization is required for dominant negative inhibition by mutations that cause thyroid hormone resistance.

Abstract excerpt

The syndrome of thyroid hormone resistance (THR) is caused by multiple distinct mutations of the ligand-binding domain of the thyroid hormone beta receptor. Although the mutant receptors are transcriptionally inactive, they inhibit normal receptor function in a dominant negative manner to cause hormone resistance. Because most of the naturally occurring mutations are clustered within two areas that lie on either...
