Claims22
A polypeptide comprising the sequence GIVEQCCX1SICSLYQLENX2CX3 (SEQ ID NO:
- 3), wherein
- X1 is selected from the group consisting of threonine and histidine;
- X2 is an amino acid of the general structure
- wherein R4 is NH2 or OCH3;
- and
- X3 is asparagine, glycine or alanine;
- or an analog thereof comprising a sequence that differs from SEQ ID NO:
- 3 by 1 to 3 amino acid modifications, selected from positions A5, A8, A9, A10, A14, A15, A17, A18.
