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
While most nuclear receptors bind DNA as homo or heterodimers, the human estrogen related receptors (hERRs) are members of a subfamily of orphan receptors that bind DNA as monomers. We have determined the solution structure of the DNA binding domain (DBD) of hERR2 bound to its cognate DNA. The structure and base interactions of the core DBD are similar to those of other nuclear receptors. However, high-affinity, sequence-specific DNA binding as a monomer necessitates formation of additional base contacts outside the core DBD. This is accomplished using a modified guanosine-binding "AT-hook" within the C-terminal extension (CTE) flanking the DBD, which makes base-specific minor groove interactions. The structure of the CTE is stabilized both by interactions with the DNA and by packing against a region of the core DBD normally reserved for dimerization. This pseudo-dimer interface provides a basis for the expansion of DNA recognition and suggests a mechanism through which dimerization may have evolved from an ancestral monomeric receptor.
