NCOR2: Proteins and Enzymes

Nuclear hormone receptors are transcription factors regulated by ligand binding. In the absence of ligand there is a physical interaction between the nuclear receptors that do not interact with Hsp90 and a family of corepressors which includes SMRT. SMRT helps target histone deacetylases and other components of a multiprotein repressor complex to the specific target promoter to silence gene transcription.
