    • The invention concerns the use of a DNA sequence comprising: a nucleotide sequence coding for an indicator protein (indicator gene); a promoter; a mutated operator; the said nucleotide sequence being under the control of the said promoter comprising the said mutated operator containing two sequences and deriving from an operator containing two inverted repeat sequences (palindrome), this mutated operator being such that one of its sequences is mutated (mutation 1), while the other is for instance wild. The transcription of the indicator gene is repressed by controlling proteins in the form of heterodimers via their DNA binding sites, each monomer of these heterodimers being such that it recognises specifically one the sequence comprising mutation 1, the other the wild sequence, in particular for detecting interactions between two proteins, these interactions being revealed when there is repression of the transcription of the said indicator gene, this repression resulting from the formation of heterodimers.
    • 本发明涉及DNA序列的用途,其包含:编码指示蛋白(指示基因)的核苷酸序列; 启动子 变异算子 所述核苷酸序列在所述启动子的控制下,所述启动子包含所述突变的操纵子,其含有两个序列,并衍生自含有两个反向重复序列(回文)的操纵子,该突变的操纵子使得其序列之一被突变(突变1) 而另一个则是野生动物。 指示基因的转录通过控制异源二聚体形式的蛋白质通过它们的DNA结合位点而被抑制,这些异源二聚体的每个单体使得它能够特异性识别一个包含突变1的序列,另一个是野生序列,特别是用于检测 两种蛋白质之间的相互作用,当抑制所述指示基因的转录时,这些相互作用被揭示,这是由形成异二聚体引起的抑制。
