Method for designing RNA binding protein utilizing PPR motif, and use thereof

摘要

Provided is a method for designing a protein capable of selectively binding RNA bases or specifically binding an RNA base sequence. This protein includes 1 or more (preferably 2-14) PPR motifs comprising a polypeptide represented by formula (1) and having a length of 30-38 amino acids (in formula (1): Helix A is a moiety which is represented by formula (2), has a length of 12 amino acids, and is capable of forming an α-helix structure (in formula (2), A
