補足情報

Estrogen Receptor alpha also known as ERα or ESR1 is a nuclear receptor that acts as a transcription factor when activated by its ligand estrogen. Its molecular weight is approximately 66 kDa. ERα is expressed in various tissues such as breast tissue endometrium and ovarian cells as well as some areas of the central nervous system. The ERα protein binds to specific DNA sequences called estrogen response elements to regulate the transcription of target genes. Tools like ER alpha ELISA and assays using alpha peptides help to study this receptor.
Biological function summary

ERα plays a significant role in the regulation of estrogen signaling. Estrogens binding to ERα activate the receptor which can form a homodimer or heterodimer complex with other proteins like coactivators or corepressors. This complex then modulates the transcription of genes involved in cell growth proliferation and differentiation. ERα is closely linked with processes like reproductive tissue development and maintenance.

Pathways

ERα is involved in the estrogen signaling pathway and the cell cycle regulation pathway. In the estrogen signaling pathway ERα works together with proteins such as coactivators which enhance gene transcription and corepressors which can inhibit transcription. In the context of cell cycle regulation ERα's interactions with other cell cycle proteins help control cell division and proliferation linking ERα activity to the progression through different stages of the cell cycle.

ERα's dysregulation has been implicated in breast cancer and osteoporosis. ERα overexpression or mutations can lead to oncogenic effects in breast cancer making it a prominent therapeutic target. Drugs that modulate ERα activity like selective estrogen receptor modulators (SERMs) are used in breast cancer treatment. In osteoporosis ERα is related to bone density regulation with its activity affecting bone resorption and formation. Relationships between ERα and other proteins such as those involved in hormone signaling pathways impact these disease mechanisms.

ターゲットの情報

The protein expressed by the gene ESR1 functions as a nuclear hormone receptor involved in regulating eukaryotic gene expression, affecting cellular proliferation and differentiation in target tissues. It mediates ligand-dependent nuclear transactivation either through direct homodimer binding to estrogen response elements (ERE) or by associating with other transcription factors like AP-1/c-Jun, c-Fos, ATF-2, Sp1, and Sp3, allowing ERE-independent signaling. Ligand binding triggers a conformational change, facilitating the interaction with coactivator complexes through LXXLL motifs. This interaction leads to mutual transrepression with NF-kappa-B in a cell-type-specific manner, reducing NF-kappa-B DNA-binding activity and transcription from the IL6 promoter while displacing coregulators like RELA/p65. It can antagonistically or synergistically interact with NF-kappa-B for transcription activation, involving recruitment to adjacent response elements, working with CREBBP. Additionally, it activates the transcription of TFF1 and mediates membrane-initiated signaling through kinase cascades. It's crucial for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3. Isoform 3 specifically activates NOS3 and endothelial nitric oxide production, while isoforms lacking certain functional domains modulate transcriptional activity by competitive ligand or DNA binding and heterodimerization with the full-length receptor, capable of binding to ERE and inhibiting isoform 1.
