Abstract

Thyroid hormone receptors (TRs) are expressed primarily as two major isoforms, TRα1 and TRβ1, which are expressed at different times in development and at different tissue abundances in the adult. The transcription properties and biological properties of TRα1 and TRβ1 can differ. We report here that although overlapping, TRα1 and TRβ1 recruit distinct panels of partner proteins that may account for their divergent biological functions, and which appear to explain their distinct target gene regulatory properties.
