作为类固醇受体与DNA相互作用的模型,研究了雌二醇受体复合物(E2 R)与共价连接在纤维素上的寡脱氧核苷酸的结合。结合是最佳的单价阳离子盐的浓度,或接近,等渗水平和细胞内受体的选择性相比,细胞外类固醇结合蛋白。在寡聚体中,亲和力的顺序为oligo dG> oligo dT≥ oligo dC> oligo dA> oligo dI。与oligo dG的结合对37° C暴露以及吸附和解吸过程是稳定的,而与oligo dT、oligo dC和oligo dA的反应性是不稳定的。纯化后结合的减少被组蛋白2B恢复。寡聚dG结合对cibacron蓝F3 GA(CB)和吡哆醛-5-磷酸的抑制作用最具抗性。在这些数据的基础上,提出了一个假设的相互作用的小鼠子宫胞液E2 R与流行的非特异性和推定的特定序列的DNA。
As a model for interaction of steroid receptors with DNA, the binding of estradiol receptor complexes (E2R) to oligodeoxynucleotides, covalently linked to cellulose, was studied in detail. Binding was optimal at concentrations of monovalent cationic salts at, or near, isotonic levels and was selective for intracellular receptors in contrast to extracellular steroid binding proteins. Among the oligomers, the order of affinity was oligo dG> oligo dT≥ oligo dC≫oligo dA≫oligo dI. The binding to oligo dG was stable to 37° C exposure and the processes of adsorption and desorption, while reactivity with oligo dT, oligo dC and oligo dA was labile. The decrease in binding following purification was restored by histone 2B. Oligo dG binding was the most resistant to inhibition by cibacron blue F3GA (CB) and pyridoxal-5-phosphate. On the basis of these data, a hypothesis is proposed for the interaction of mouse uterine cytosol E2R with prevalent nonspecific and putative specific sequences of DNA.
