亚单元:
Interacts with BCAS3. Binds DNA as a homodimer (By similarity). Can form a heterodimer with ESR2 (By similarity). Interacts with coactivator NCOA5. Interacts with NCOA7; the interaction is ligand-inducible. Interacts with AKAP13, CUEDC2, HEXIM1, KDM5A, MAP1S, PELP1, SMARD1, and UBE1C. Interacts with MUC1; the interaction is stimulated by 7 beta-estradiol (E2) and enhances ERS1-mediated transcription. Interacts with DNTTIP2, and UIMC1. Interacts with KMT2D/MLL2. Interacts with ATAD2; the interaction is enhanced by estradiol. Interacts with KIF18A and LDB1. Interacts with RLIM (via its C-terminus). Interacts with MACROD1. Interacts with SH2D4A and PLCG. Interacts with SH2D4A; the interaction blocks binding to PLCG and inhibits estrogen-induced cell proliferation. Interacts with DYNLL1. Interacts with CCDC62; the interaction requires estradiol and appears to enhance the transcription of target genes. Interacts with NR2C1; the interaction prevents homodimerization of ESR1 and suppresses its transcriptional activity and cell growth. Interacts with DYX1C1. Interacts with PRMT2. Interacts with PI3KR1 or PIK3R2, SRC and PTK2/FAK1. Interacts with RBFOX2. Interacts with EP300; the interaction is estrogen-dependent and enhanced by CITED1. Interacts with CITED1; the interaction is estrogen-dependent (By similarity). Interacts with FAM120B, FOXL2, PHB2 and SLC30A9. Interacts with coactivators NCOA3 and NCOA6. Interacts with STK3/MST2 only in the presence of SAV1 and vice-versa. Binds to CSNK1D. Interacts with NCOA2; NCOA2 can interact with ESR1 AF-1 and AF-2 domains simultaneously and mediate their transcriptional synergy. Interacts with DDX5. Interacts with NCOA1; the interaction seems to require a self-association of N-terminal and C-terminal regions. Interacts with ZNF366, DDX17, NFKB1, RELA, SP1 and SP3. Interacts with NRIP1 (By similarity). Interacts with GPER1; the interaction occurs in an estrogen-dependent manner (By similarity). Interacts with TRIP4 (ufmylated); estrogen dependent (By similarity). Interacts with LMTK3; the interaction phosphorylates ESR1 (in vitro) and protects it against proteasomal degradation. Interacts with CCAR2 (via N-terminus) in a ligand-independent manner. Interacts with ZFHX3 (By similarity). Interacts with SFR1 in a ligand-dependent and -independent manner (By similarity). Interacts with DCAF13, LATS1 and VPRBP; regulates ESR1 ubiquitination and ubiquitin-mediated proteasomal degradation. Interacts (via DNA-binding domain) with POU4F2 (C-terminus); this interaction increases the estrogen receptor ESR1 transcriptional activity in a DNA- and ligand 17-beta-estradiol-independent manner.
功能:
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.

大鼠雌激素受体(Esr1)重组蛋白是否是无菌的？
蛋白试剂瓶和蛋白保存液是经过高压灭菌的，但也不能保证蛋白是完全无菌的。如果要求蛋白是无菌的，可以用0.2微米的滤器对蛋白进行过滤。
[2].
大鼠雌激素受体(Esr1)重组蛋白的保存缓冲液是什么？
纯化后的蛋白保存在PBS（58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.4）里，并往里面加入500mM咪唑和10%甘油。
[3].
怎样确定大鼠雌激素受体(Esr1)重组蛋白的浓度？
蛋白浓度的确定没有一个统一的标准，这主要取决于蛋白的氨基酸序列。伊艾博是根据不同测试的组合来测定蛋白浓度。考马斯亮蓝法、BCA法、氨基酸序列和氨基酸全序列分析法等都用来测定蛋白浓度。
[4].
大鼠雌激素受体(Esr1)重组蛋白蛋白保存条件是怎样的？
蛋白应保存在 -20℃或 -80℃条件下，为了避免反复冻融，可以将蛋白分装成小份保存。
[5].
大鼠雌激素受体(Esr1)重组蛋白是否可以用于活体实验？
重组蛋白没有用于任何的活体实验，因此蛋白的活性和半衰期是不确定的。
[6].
大鼠雌激素受体(Esr1)重组蛋白的保质期是多久？
在适当的保存条件下，从购买之日起蛋白可以稳定保存6-12个月。适当的保存条件是:蛋白保存在-20°C o或 -80℃，保证蛋白的保存浓度高于0.1mg/ml，限制蛋白反复冻融的次数。我们公司常规的质量检测保证所有产品在销售时都有可接受的生物活性。但是我们不能控制终端用户蛋白的保存条件。如果产品在有效期内出现问题，请联系我们的技术支持。
[7].
你们蛋白和抗体的报价是怎么样的？
我们将根据你需要的蛋白和抗体的大小进行报价。
[8].
大鼠雌激素受体(Esr1)重组蛋白是否能够提供蛋白片段？
我们现有的人的蛋白的序列可以有很多。你可以选择你感兴趣的靶向部分，我们将会按您的需求提供蛋白和抗体。
[9].
大鼠雌激素受体(Esr1)重组蛋白的货期或发货时间一般是多长？
具体指标的货期需要确定。最快一周，最长可能一个月。
