Disease

[NCOA1_HUMAN] Note=A chromosomal aberration involving NCOA1 is a cause of rhabdomyosarcoma. Translocation t(2;2)(q35;p23) with PAX3 generates the NCOA1-PAX3 oncogene consisting of the N-terminus part of PAX3 and the C-terminus part of NCOA1. The fusion protein acts as a transcriptional activator. Rhabdomyosarcoma is the most common soft tissue carcinoma in childhood, representing 5-8% of all malignancies in children.

Function

[ERR3_HUMAN] Orphan receptor that acts as transcription activator in the absence of bound ligand. Binds specifically to an estrogen response element and activates reporter genes controlled by estrogen response elements (By similarity).^[1] ^[2] ^[3] [NCOA1_HUMAN] Nuclear receptor coactivator that directly binds nuclear receptors and stimulates the transcriptional activities in a hormone-dependent fashion. Involved in the coactivation of different nuclear receptors, such as for steroids (PGR, GR and ER), retinoids (RXRs), thyroid hormone (TRs) and prostanoids (PPARs). Also involved in coactivation mediated by STAT3, STAT5A, STAT5B and STAT6 transcription factors. Displays histone acetyltransferase activity toward H3 and H4; the relevance of such activity remains however unclear. Plays a central role in creating multisubunit coactivator complexes that act via remodeling of chromatin, and possibly acts by participating in both chromatin remodeling and recruitment of general transcription factors. Required with NCOA2 to control energy balance between white and brown adipose tissues. Required for mediating steroid hormone response. Isoform 2 has a higher thyroid hormone-dependent transactivation activity than isoform 1 and isoform 3.^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10]

Publication Abstract from PubMed

The estrogen-related receptor (ERR) gamma behaves as a constitutive activator of transcription. Although no natural ligand is known, ERRgamma is deactivated by the estrogen receptor (ER) agonist diethylstilbestrol and the selective ER modulator 4-hydroxytamoxifen but does not significantly respond to estradiol or raloxifene. Here we report the crystal structures of the ERRgamma ligand binding domain (LBD) complexed with diethylstilbestrol or 4-hydroxytamoxifen. Antagonist binding to ERRgamma results in a rotation of the side chain of Phe-435 that partially fills the cavity of the apoLBD. The new rotamer of Phe-435 displaces the "activation helix" (helix 12) from the agonist position observed in the absence of ligand. In contrast to the complexes of the ERalpha LBD with 4-hydroxytamoxifen or raloxifene, helix 12 of antagonist-bound ERRgamma does not occupy the coactivator groove but appears to be completely dissociated from the LBD body. Comparison of the ligand-bound LBDs of ERRgamma and ERalpha reveals small but significant differences in the architecture of the ligand binding pockets that result in a slightly shifted binding position of diethylstilbestrol and a small rotation of 4-hydroxytamoxifen in the cavity of ERRgamma relative to ERalpha. Our results provide detailed molecular insight into the conformational changes occurring upon binding of synthetic antagonists to the constitutive orphan receptor ERRgamma and reveal structural differences with ERs that explain why ERRgamma does not bind estradiol or raloxifene and will help to design new selective antagonists.

Structural basis for the deactivation of the estrogen-related receptor gamma by diethylstilbestrol or 4-hydroxytamoxifen and determinants of selectivity.,Greschik H, Flaig R, Renaud JP, Moras D J Biol Chem. 2004 Aug 6;279(32):33639-46. Epub 2004 May 24. PMID:15161930^[11]
