Claim:
1. A recombinant fusion protein comprising the moieties B and CT, wherein: B is a non-spidroin moiety which provides the capacity of selective interaction with an organic target, wherein B is a protein or polypeptide fragment comprising more than 30 amino acid residues, and wherein B is a moiety selected from the group consisting of the Z domain derived from CT is a moiety of from 70 to 120 amino acid residues, has at least 80% identity to SEQ ID NO: 7, and provides the capacity of forming a polymer; with the proviso that the fusion protein has less than 30% identity to any of SEQ ID NO: 10-13 and does not comprise an amino acid sequence of from 8 to 18 amino acid residues, of which from 0 to 3 are not alanine residues and the remaining amino acid residues are alanine residues.
