Thyroid Hormone Receptor

The thyroid hormone receptor (THR) is a type of nuclear receptor which belongs to a superfamily of eukaryotic transcription factors. It regulates gene expression in response to binding small, hydrophobic ligands. The receptors exhibits a modular structure, with functionally separable domains. The most highly conserved domains are the DNA-binding domain (DBD) and the ligand-binding domain (LBD). The DBD recognizes the specific DNA responses element for the receptor. The LBD participates in several activities, including hormone binding, homo- and/or heterodimerization, formation of heat-shock-protein complex, and transcriptional activation and repression. Unliganded thyroid hormone receptors are bound to DNA thyroid hormone response elements predominantly as homodimers, or as heterodimers with retinoid X-receptors, and are associated with a complex of proteins containing corepressor proteins. Ligand binding promotes corepressor dissociation and binding of a coactivator. Hormone binding induces changes in receptor conformation that control these properties and influence gene expression.
