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.
Isoform 3 is involved in activation of NOS3 and endothelial nitric oxide production.
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.
Isoform 3 can bind to ERE and inhibit isoform 1.
