The present invention provides a crosslinking agent which have photodegradable protective groups at two ends to crosslink double-stranded nucleic acid, a nucleic acid and a protein or a polypeptide, or proteins or polypeptides, in particular, double-stranded RNA; a method for crosslinking a double-stranded RNA or the like using the same; a method for regulating gene expression, which can control the expression of a target gene at an arbitrary timing and location; and a method for examining a gene function.
According to the present invention, crosslinking between double-stranded nucleic acids between a nucleic acid and a protein or a polypeptide, or between proteins or polypeptides, in particular, between double-stranded RNA can be easily formed, and in addition, the crosslinking can also be easily removed, so that the expression of a target gene can be easily controlled at an arbitrary timing and location with high efficiency. Hence, as a result, function examination and/or identification of a gene that is expressed at a specific timing and location can be performed. In addition, the RNAi effect of a double-stranded RNA (siRNA) that cannot be easily inhibited by a conventional caged compound can be inhibited, and the expression of a target gene can be easily controlled at an arbitrary timing and location.
本发明提供了一种交联剂,其在两端具有光降解保护基团,用于交联双链核酸、核酸和蛋白质或多肽,或蛋白质或多肽,特别是双链RNA;一种使用该交联剂交联双链RNA或类似物的方法;一种调节基因表达的方法,可以在任意时机和位置控制目标基因的表达;以及一种检查基因功能的方法。根据本发明,双链核酸之间、核酸和蛋白质或多肽之间,或蛋白质或多肽之间,特别是双链RNA之间的交联可以很容易地形成,此外,交联也可以很容易地去除,因此可以高效地在任意时机和位置轻松控制目标基因的表达。因此,可以执行在特定时机和位置表达的基因的功能检查和/或鉴定。此外,可以抑制传统光遮蔽化合物难以抑制的双链RNA(siRNA)的RNAi效应,并且可以在任意时机和位置轻松控制目标基因的表达。
