| 产品介绍 | Estrogen and progesterone receptor are members of a family of transcription factors that are regulated by the binding of their cognate ligands. The interaction of hormone-bound estrogen receptors with estrogen responsive elements(EREs) alters transcription of ERE-containing genes. The carboxy terminal region of the estrgen receptor contains the ligand binding domain, the amino terminus serves as the transactivation domain, and the DNA binding domain is centrally located. Two forms of estrogen receptor have been identified, ER alpha and ER beta. ER alpha and ER beta have been shown to be differentially activated by various ligands. The biological response to progesterone is mediated by two distinct forms of the human progesterone receptor (hPR-Aand hPR-B), which arise from alternative splicing. In most cells, hPR-B functions as a transcriptional activator of progesterone-responsive gene, whereas hPR-A function as a transcriptional inhibitor of all steroid hormone receptors. Function: The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Progesterone receptor isoform B (PRB) is involved activation of c-SRC/MAPK signaling on hormone stimulation. Isoform A is inactive in stimulating c-Src/MAPK signaling on hormone stimulation. Subunit: Interacts with SMARD1 and UNC45A. Interacts with CUEDC2; the interaction promotes ubiquitination, decreases sumoylation, and repesses transcriptional activity. Interacts with PIAS3; the interaction promotes sumoylation of PR in a hormone-dependent manner, inhibits DNA-binding, and alters nuclear export. Interacts with SP1; the interaction requires ligand-induced phosphorylation on Ser-345 by ERK1/2 MAPK. Interacts with PRMT2. Subcellular Location: Nucleus. Cytoplasm. Note=Nucleoplasmic shuttling is both homone- and cell cycle-dependent. On hormone stimulation, retained in the cytoplasm in the G(1) and G(2)/M phases. Isoform A: Nucleus. Cytoplasm. Note=Mainly nuclear. Post-translational modifications: Phosphorylated on multiple serine sites. Several of these sites are hormone-dependent. Phosphorylation on Ser-294 occurs preferentially on isoform B, is highly hormone-dependent and modulates ubiquitination and sumoylation on Lys-388. Phosphorylation on Ser-102 and Ser-345 also requires induction by hormone. Basal phosphorylation on Ser-81, Ser-162, Ser-190 and Ser-400 is increased in response to progesterone and can be phosphorylated in vitro by the CDK2-A1 complex. Increased levels of phosphorylation on Ser-400 also in the presence of EGF, heregulin, IGF, PMa and FBS. Phosphorylation at this site by CDK2 is ligand-independent, and increases nuclear translocation and transcriptional activity. Phosphorylation at Ser-162 and Ser-294, but not at Ser-190, is impaired during the G(2)/M phase of the cell cycle. Phosphorylation on Ser-345 by ERK1/2 MAPK is required for interaction with SP1. Sumoylation is hormone-dependent and represses transcriptional activity. Sumoylation on all three sites is enhanced by PIAS3. Desumoylated by SENP1. Sumoylation on Lys-388, the main site of sumoylation, is repressed by ubiquitination on the same site, and modulated by phosphorylation at Ser-294. Similarity: Belongs to the nuclear hormone receptor family. NR3 subfamily. Contains 1 nuclear receptor DNA-binding domain.

文献和实验孕激素受体 (PR) PR基因定位于染色体1lql3，其基因第一个外显子区有一CpG岛。PR基因编码两个异构体：hPRA和hPRB，它们的N端序列与生物活性不同。与配体结合的雌激素受体是hPRB转录必需因子，hPRB表达说明功能性ER存在。用DNA印迹法分析表明，约40％的PR阴性乳腺癌组织和PR阳性的肿瘤细胞系都发现PR基因甲基化。在雌激素存在的条件下，用5―氮杂―2―脱氧胞苷处理PR阴；陛的MDA―MB―231细胞，可使PR基因CpG岛部分脱甲基化和PR

在生命科学和医学基础研究中，或多或少都需要用到抗体。抗体的应用场景不同、标记物众多，且针对同一标记物市场上往往有多个抗体可供选择，那么，我们如何从成百万上千万种抗体中，挑选出我们想要的那支呢？ 在我们6月份的关于抗体的调研活动中，我们发现，大家更多的是去参考文献或专利中的材料和方法部分，这无疑很大程度上保证了抗体的有效性。其次有45%和34%的受访者会用到百度和谷歌，然而这两个搜索引擎覆盖面颇广，经常会出现抗体无关的搜索结果，而专业用于查找抗体的网站，大家却知之甚少。 因此，本次文章中
