Disease

ERR2_HUMAN Defects in ESRRB are the cause of deafness autosomal recessive type 35 (DFNB35) [MIM:608565. DFNB35 is a form of sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.^[1]

Function

ERR2_HUMAN Nuclear receptor, may regulate ESR1 transcriptional activity.^[2]

Publication Abstract from PubMed

Estrogen-related receptor beta (ERRbeta) is a nuclear receptor critical for many biological processes. Despite the biological and pharmaceutical importance of ERRbeta, deciphering the structure of ERRbeta has been hampered by the difficulties in obtaining a pure and stable protein for structural studies. In fact, the ERRbeta ligand-binding domain remains the last unsolved ERR structure and also one of only a few unknown nuclear receptor structures. Here, we report the identification of a critical single-residue mutation resulted in robust solubility and stability of an active ERRbeta ligand-binding domain, thereby providing a protein tool enabling the first probe into the biochemical and structural studies of this important receptor. The crystal structure reveals key structural features that have enabled the integration of the molecular determinants of signals transduced across the ligand binding and coregulator recruitment by all three ERR subtypes, which also provides a framework for the rational design of selective and potent ligands for the treatment of various ERR-mediated diseases.
