PEPTIDE-PRESENTING PROTEIN AND PEPTIDE LIBRARY EMPLOYING SAME

摘要

The purpose of the present invention is to provide a method for screening peptides displaying high specificity to a target molecule. The problem is solved by a peptide-presenting protein presenting a peptide in a presentation region from 131-139 in an amino acid sequence represented by SEQ ID NO: 54, wherein the peptide-presenting protein presents an amino acid sequence of 4-15 peptides inserted into the amino acid sequence of 131-139, or 1-9 amino acid sequences substituted into the amino acid sequence of 131-139, the chain length of the amino acid sequence corresponding to the amino acid sequence of 131-139 being 15 or less.
