Peptide and composition

Abstract

The present invention addresses the problem of providing a peptide or a composition which can promote the healing of a wound at a dentin-pulp complex. The problem can be solved by a peptide that comprises an amino acid sequence comprising Lys-Leu-Leu-Glu-Thr-Glu-Cys-Pro-Gln (SEQ ID NO: 28), an amino acid sequence comprising Asn-Thr-Asp-Gly-Ala-Val-Asn-Phe-Gln (SEQ ID NO: 32), an amino acid sequence comprising Glu-Leu-Val-Arg-Lys-Asp-Leu-Gln-Asn (SEQ ID NO: 47), an amino acid sequence comprising Asn-Ala-Asp-Lys-Gln-Leu-Ser-Phe-Glu (SEQ ID NO: 51), an amino acid sequence having such a structure that 1 to 3 amino acid residues in the amino acid sequence represented by SEQ ID NO: 28, SEQ ID NO: 32, SEQ ID NO: 47 or SEQ ID NO: 51 are substituted or deleted, or an amino acid sequence having such a structure that 1 to 3 amino acid residues are inserted into the amino acid sequence represented by SEQ ID NO: 28, SEQ ID NO: 32, SEQ ID NO: 47 or SEQ ID NO: 51, the peptide having a length of 9 to 15 amino acid residues.
