Claim One:
1. A product selected from: a polypeptide, the sequence of which consists of less than 100 amino acids, comprising: the sequence of SEQ ID NO: 6, or a sequence, which: is of 34 to 54 amino acids, is at least 94% identical to said sequence of SEQ ID NO: 6 over the entire length of the shortest of the two sequences, comprises a PDZ-BS sequence, wherein said PDZ-BS sequence is: x 1 is any amino acid except E, and x 2 is T or S or I, and x 3 is any amino acid, and x 4 is L or V (SEQ ID NO: 14), said sequence being referred to as variant sequence A, or a sequence, which: is of 44 amino acids, is at least 94% identical to said sequence of SEQ ID NO: 6, comprises a PDZ-BS sequence, wherein said PDZ-BS sequence is: x 1 is E, and x 2 is T or S or I, and x 3 is any amino acid, and x 4 is L or V (SEQ ID NO: 13 with x 1 =E), and does not comprise the amino acid L at position 11, said sequence being referred to as variant sequence B, or a fragment of said sequence of SEQ ID NO: 6 or of said variant sequence A or of said variant sequence B, wherein said fragment is of at least 34 amino acids and has retained the PDZ-BS sequence of said sequence of SEQ ID NO: 6 or of said variant sequence A or of said variant sequence B, respectively, or a nucleic acid coding for said polypeptide, or a vector comprising said nucleic acid, or a cell comprising said polypeptide and/or said nucleic acid and/or said vector, or a pharmaceutical composition or drug, comprising at least one of said polypeptide, nucleic acid, vector and cell.
