Abstract:
A substantially pure polypeptide which comprises an amino acid subsequence S having a length of 20 amino acids, said subsequence S comprising at least one sequence element selected from the group consisting of the tetrapeptides DGEA (Asp-Gly-Glu-Ala), VTKG (Val-Thr-Lys-Gly), EKGE (Glu-Lys-Gly-Glu) and DKGE (Asp-Lys-Gly-Glu),which subsequence S has a percentage sequence identity of at least 80% with at least one 20 amino acid reference subsequence of a reference sequence selected from the group consisting of (a) the amino acid sequence shown in SEQ ID NO:2, and (b) the amino acid sequence shown in SEQ ID:4, the reference subsequence likewise comprising said sequence element.
