Abstract: An object of the present invention is to provide an antisense guide RNA for editing a polyadenylation signal sequence of a target RNA and a nucleic acid that encodes the guide RNA, which are expected to control expression of the target RNA with high efficiency. The present inventors have intensively examined technologies for controlling expression of a target RNA with high efficiency, thereby completing the present invention by discovering a guide RNA for ADAR-dependent editing of the target RNA, including an antisense region complementary to a portion of the target RNA including a polyadenylation signal sequence.

Abstract: Object: To provide an antisense guide RNA for editing a target RNA by ADAR. Solution: An antisense guide RNA for editing a target RNA by ADAR, containing at least one functional region and an antisense region that is complementary to a portion of the target RNA and can form a double strand with the target RNA, in which the at least one functional region is linked to the antisense region, and in which the guide RNA does not substantially contain an ADAR-recruiting base sequence.

Abstract: [Problem to be Solved] To provide a guide RNA. [Solution] A guide RNA for editing a target RNA sequence, comprising an antisense nucleotide sequence complementary to a portion of the target RNA sequence, a short-chain ADAR-recruiting nucleotide sequence, and at least one functional nucleotide sequence.
