DNA constructs and other compositions and methods for controlling gene expression in eukaryotic cells and organisms are derived from bacterial quorum sensing systems. One or more cis elements from the lux1 promoter ("lux box") or a functionally similar sequence are incorporated in a eukaryotic promoter. A receptor protein from the LuxR family of transcriptional regulators, upon binding an acylated homoserine lactone (AHL) compound, interacts with the lux box, modulating the activity of the promoter.
控制真核细胞和生物体内基因表达的DNA构建体和其他组合物及方法源自细菌的法定量感应系统。一个或多个来自lux1启动子("lux box")的顺式元件或功能类似的序列被整合到真核启动子中。转录调节器LuxR家族的受体蛋白在与酰化高丝氨酸内酯(AHL)化合物结合后,会与lux盒相互作用,调节启动子的活性。
