Abstract

A recombinant fusion protein comprising the moieties B and CT is provided. B is a non-spidroin moiety which provides the capacity of selective interaction with an organic target. CT is a moiety of from 70 to 120 amino acid residues and is derived from the C-terminal fragment of a spider silk protein. The fusion protein is not comprising any moiety derived from the repetitive fragment of a spider silk protein.
