Protein complex binding motif sequence containing two RNA-protein binding motif sequences and a double-stranded RNA having functional molecules at both ends and a protein binding to the RNA-protein binding motif sequence at 2 An RNA-protein complex containing a protein obtained by fusing a double-stranded RNA containing at least one double-stranded RNA and a protein binding to the RNA-protein binding motif sequence and an agglutinated protein is designed.RNA-タンパク質結合モチーフ配列を2つ含み、両端に機能的分子を有する2重鎖RNAと当該RNA-タンパク質結合モチーフ配列へ結合するタンパク質を含むRNA-タンパク質複合体またはRNA-タンパク質結合モチーフ配列を2つ以上含む2重鎖RNAと当該RNA-タンパク質結合モチーフ配列へ結合するタンパク質と被凝集タンパク質を融合したタンパク質を含むRNA-タンパク質複合体を設計する。
