Ligands specify coactivator nuclear receptor (NR) box affinity for estrogen receptor subtypes.
Nuclear receptors (NRs) require coactivators to efficiently activate transcription of their target genes. Many coactivators including the p160 proteins utilize a short NR box motif to recognize the ligand-binding domain of the NR when it is activated by ligand. To investigate the ability of various ligands to specify the affinity of NR boxes for a ligand-bound NR, we compared the capacity of p1...
متن کاملPrediction and analysis of ligands against estrogen related receptor alpha.
Breast cancer is one of the most common malignancies in women around the world. Among the various hormonal types of breast cancer, those that are estrogen receptor (ER) positive account for the majority. Among the estrogen related receptors, estrogen related receptor α is known to have a potential role in breast cancer and is one of the therapeutic target. Hence, prediction of novel ligands int...
متن کاملNuclear localization signal receptor importin alpha associates with the cytoskeleton.
Importin alpha is the nuclear localization signal (NLS) receptor that is involved in the nuclear import of proteins containing basic NLSs. Using importin alpha as a tool, we were interested in determining whether the cytoskeleton could function in the transport of NLS-containing proteins from the cytoplasm to the nucleus. Double-labeling immunofluorescence studies showed that most of the cytopl...
متن کاملThe aryl hydrocarbon receptor mediates degradation of estrogen receptor alpha through activation of proteasomes.
2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other aryl hydrocarbon receptor (AhR) ligands suppress 17beta-estradiol (E)-induced responses in the rodent uterus and mammary tumors and in human breast cancer cells. Treatment of ZR-75, T47D, and MCF-7 human breast cancer cells with TCDD induces proteasome-dependent degradation of endogenous estrogen receptor alpha (ERalpha). The proteasome inhib...
متن کاملEstrogen receptor alpha: impact of ligands on intracellular shuttling and turnover rate in breast cancer cells.
Estrogen receptors (alpha and beta) are members of the steroid/thyroid nuclear receptors superfamily of ligand-dependent transcription factors. Impact of the alpha isoform of estrogen receptor (ER) on breast cancer etiology and progression is now well established. Current therapeutic strategy to treat ER-positive breast cancer relies on the blockade of ER trancriptional activity by antiestrogen...
