雌激素受体-α(ERα)对基因表达的调控需要不同转录辅调节因子复合物的协调和临时募集,这些转录辅调节因子复合物介导核小体重塑和组蛋白修饰。以ERα为诱饵,通过酵母双杂交筛选,我们发现了一个新的ERα相互作用蛋白ZNF 366,它是一个有效的ERα活性辅阻遏物。ZNF 366与ERα之间的相互作用已在体内外得到证实,并通过两种蛋白的锌指结构域介导。此外,我们发现ZNF 366作为一个辅阻遏物,通过与其他已知的ERα辅阻遏物,即RIP 140和CtBP,抑制雌激素反应基因的表达在体内。总之,我们的研究结果表明,ZNF 366可能在调节雌激素应答基因的表达中发挥重要作用。
The regulation of gene expression by estrogen receptor-α (ERα) requires the coordinated and temporal recruitment of diverse sets of transcriptional co-regulator complexes, which mediate nucleosome remodelling and histone modification. Using ERα as bait in a yeast two-hybrid screen, we have identified a novel ERα-interacting protein, ZNF366, which is a potent corepressor of ERα activity. The interaction between ZNF366 and ERα has been confirmed in vitro and in vivo, and is mediated by the zinc finger domains of the two proteins. Further, we show that ZNF366 acts as a corepressor by interacting with other known ERα corepressors, namely RIP140 and CtBP, to inhibit expression of estrogen-responsive genes in vivo. Together, our results indicate that ZNF366 may play an important role in regulating the expression of genes in response to estrogen.
