oestrogen transcription factor
Estrogen regulates the expression of various genes, such as peroxidase, cadherin, adenine nuclear transcription factor, heat shock protein, and phosphatase inhibitor. 1. The oestrogen receptor with combined co-factors stimulates RNA polymerase to transcribe that target gene. A transcription factor is a protein that binds to a gene's promoter region and as a result enables RNA polymerase to attatch to the start of the gene and begin its transcription. This assay combines a quick ELISA format with a sensitive and specific non-radioactive assay for transcription factor activation. Oestrogen receptor-α (ERα)-regulated transcription in breast cancer cells involves protein co-factors that contribute to the regulation of chromatin structure. The functions of many transcription factors are regulated through protein kinase-mediated phosphorylation, and these transcription factors may thus be targets for nongenomic actions of estrogens, as illustrated in Fig. Hormones like oestrogen can switch on a gene and start transcription.They do this by binding to their receptor on the transcription factor.This changes the transcription factors shape, and thus releases the inhibitor molecule.The transcription factor can then bind to DNA, starting up the process of transcription. factor NF-kB has a role in many pathological conditions with inflammatory and autoimmune components. The assortment of coactivator proteins implicated in estrogen signaling includes three distinct but related p160 family members, SRC-1, TIF2 or GRIP-1, and AIB1 (also referred to as ACTR, RAC3, pCIP, or NCoA-3) (39, 1, 11, 27, 34, 48) and the histone acetylases CBP, p300 (10, 25) and the p300/CBP-associated factor, pCAF (Blanco et al. Coregulators critically regulate ERα transcription functions by directly interacting with it. Oestrogen receptor-α (ERα) is a ligand-dependent transcription factor that primarily mediates oestrogen (E2)-dependent gene transcription required for mammary gland development. ERα and ERβ regulate different gene expression, and therefore, factors that regulate the expression or activation of ERα and ERβ have attracted much attention. Estrogen Receptor Transcription Factor Assay Kit (Colorimetric) (ab207203) is a high throughput assay to quantify Estrogen Receptor (ER) activation in nuclear extracts. Hormones like oestrogen can switch on a gene and thus start transcription by combining with a _____ on the transcriptional factor phospholipid Oestrogen is a lipid soluble molecule and therefore diffuses easily through the _____________ portion of cell-surface membranes The estrogen receptor (ER) is a ligand-activated enhancer protein that belongs to the steroid/nuclear receptor superfamily and functions as a signal transducer and transcription factor to modulate expression of target genes. Estrogen receptors (ERs) are transcription factors that mediate the biological responses to the sex hormone estrogen and are essential for reproduction and for functions of the cardiovascular, skeletal and nervous systems. No effect of oestrogen was observed in cultured spinal cord astroglia. Estrogen signaling is an example of a fairly short signaling cascade that involves the estrogen receptor transcription factor: Estrogen is secreted by tissues such as the ovaries and placenta, crosses the cell membrane of the recipient cell, and is bound by the estrogen receptor in the cell's cytoplasm.
