Patent ID: 7867491

Claim:
A polypeptide represented by the following formula: N′—(Z1) p —Y—Z2—Z3—Z4—C′ wherein N′ is the N-terminus and C′ is the C-terminus of the polypeptide, Z1 is an amino acid sequence consisting of the amino acid residues at positions 90 to 98 of SEQ ID NO:14; Y is an amino acid sequence consisting of 5 or more consecutive amino acid residues from the C-terminus at positions 99 to 162 of SEQ ID NO:14; Z2 is an amino acid sequence consisting of the amino acid residues at positions 163 to 170 of SEQ ID NO:14; Z3 is an amino acid sequence consisting of the amino acid residues at positions 121 to 220 of SEQ ID NO: 13; Z4 is an amino acid sequence consisting of the amino acid residues at positions 221 to 327 of SEQ ID NO: 13; and p is an integer of 0 or 1.
