Nuclear corepressors enhance the dominant negative activity of mutant receptors that cause resistance to thyroid hormone.

Abstract excerpt

The syndrome of resistance to thyroid hormone (RTH) is caused by multiple distinct mutations in the ligand-binding domain of the thyroid hormone receptor-beta (TRbeta). Although the mutant receptors are transcriptionally inactive, they inhibit normal receptor function in a dominant negative manner to cause hormone resistance. Recently, a group of transcriptional cofactors, referred to as corepressors (CoRs), was...
