DNA binding | |
Structure | Monomer, homodimer |
HRE core sequence | TNA AGGTCA (DR-3, ERE, SFRE)4 |
Partners | Calmodulin (physical, functional): interaction with calmodulin in vitro in a Ca2+-dependent manner5; DAX1 (physical, functional): inhibition of PGC1α -mediated ERRγ transactivation by competing for the AF-2 binding domain6; SHP (physical, functional): inhibition of transcriptional activity7 |
Agonists | 5,7,4′-Trihydroxyisoflavone, 7,4′-dihydroxyisoflavone, 5,7-dihydroxy-4′-methoxyisoflavone, N′-{(1E)-[4-(diethylamino)phenyl]methylene}-4-hydroxybenz ohydrazide)8,9; GSK9089 (substituted phenolic acyl hydrazones) (0.66 μM), GSK4716 (substituted phenolic acyl hydrazones) (2 μM) [IC50]10 |
Antagonists | 4-Hydroxytamoxifen (35 nM) [Kd]11; diethylstilbestrol (5–15 μM) [IC50]11,12 |
Coactivators | PNRC2, PPARGC1A, PPARGC1B, NCOA1, TLE113–15 |
Corepressors | |
Biologically important isoforms | ERRγ2 {Hs, Mm}: differs from ERRγ1 by an additional 23 N-terminal residues16; ERRγ3 {Hs}: ERRγ3 variant consists of eight exons including three unique 5′-terminal exons and lacks the exon encoding the second zinc finger motif; the expression of ERRγ3 was confined to adipocytes and prostate, whereas that of ERRγ2 was fairly widespread; the ERRγ3 variant was shown by transactivation assay to have no ability to activate ERE-controlled transcription; however, ERRγ3 has an ability to modulate the transcriptional activity of other nuclear hormone receptors17 |
Tissue distribution | Brain, kidney, testis, lung, adrenal gland, pancreas, and bone marrow {Hs, Mm} [Northern blot, RT-PCR, in situ hybridization, Western blot, immunohistology]1,2,3,18 |
Functional assays | |
Main target genes | Activated: ERRα {Hs},19 DAX-1 {Mm},6 MAOA, and MAOB {Hs, Mm, Rn}20 |
Mutant phenotype | Homozygous mutant mice do not survive to weaning age; heterozygous mice exhibit a significant increase in overall startle amplitude, indicating a possible hypersensitivity to sound-induced motor reflex in these mice {Mm} [disruption caused by insertion of a vector] |
Human disease |
aa, amino acids; chr., chromosome; HRE, hormone response element; PPARGC, coactivator gene; RT-PCR, reverse transcription-polymerase chain reaction; MAO, monoamine oxidase; ERE, estrogen response element; SFRE, SF-1 response element
