Background
| Function | FUNCTION: Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling. Ligand binding induces a conformational change allowing subsequent or combinatorial association with multiprotein coactivator complexes through LXXLL motifs of their respective components. Mutual transrepression occurs between the estrogen receptor (ER) and NF-kappa-B in a cell-type specific manner. Decreases NF-kappa-B DNA-binding activity and inhibits NF-kappa-B-mediated transcription from the IL6 promoter and displace RELA/p65 and associated coregulators from the promoter. Recruited to the NF-kappa-B response element of the CCL2 and IL8 promoters and can displace CREBBP. Present with NF-kappa-B components RELA/p65 and NFKB1/p50 on ERE sequences. Can also act synergistically with NF-kappa-B to activate transcription involving respective recruitment adjacent response elements; the function involves CREBBP. Can activate the transcriptional activity of TFF1. Also mediates membrane-initiated estrogen signaling involving various kinase cascades. Essential for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3 (PubMed:17922032). {ECO:0000269|PubMed:10681512, ECO:0000269|PubMed:10816575, ECO:0000269|PubMed:11477071, ECO:0000269|PubMed:11682626, ECO:0000269|PubMed:14764652, ECO:0000269|PubMed:15078875, ECO:0000269|PubMed:15891768, ECO:0000269|PubMed:16043358, ECO:0000269|PubMed:16617102, ECO:0000269|PubMed:16684779, ECO:0000269|PubMed:17922032, ECO:0000269|PubMed:17932106, ECO:0000269|PubMed:18247370, ECO:0000269|PubMed:19350539, ECO:0000269|PubMed:20074560, ECO:0000269|PubMed:20705611, ECO:0000269|PubMed:21330404, ECO:0000269|PubMed:22083956, ECO:0000269|PubMed:7651415, ECO:0000269|PubMed:9328340}.; FUNCTION: [Isoform 3]: Involved in activation of NOS3 and endothelial nitric oxide production (PubMed:21937726). Isoforms lacking one or several functional domains are thought to modulate transcriptional activity by competitive ligand or DNA binding and/or heterodimerization with the full-length receptor (PubMed:10970861). Binds to ERE and inhibits isoform 1 (PubMed:10970861). {ECO:0000269|PubMed:10970861, ECO:0000269|PubMed:21937726}. |
