An object of the present invention is to construct an mRNA which specifically responds to a short RNA sequence and can activate, repress, and regulate the translation of the desired gene, and to construct an artificial cell model system using a liposome comprising the mRNA and a cell-free translational system encapsulated therein. The present invention provides: an mRNA comprising a target RNA-binding site located immediately 5' to the ribosome-binding site, and a nucleotide sequence located 5' to the target RNA-binding site, the nucleotide sequence being complementary to the ribosome-binding site; an mRNA comprising a small RNA-binding site located 3' to the start codon, and a nucleotide sequence located 3' to the small RNA-binding site, the nucleotide sequence encoding a protein; and a liposome comprising any of these mRNAs encapsulated therein. |
