An isolated protein structure comprising an amino acid sequence that has at least 75% identity of SEQ ID NO: 16, which has 7 strains and 6 loops between the strains, and which comprises the amino acid sequence SEQ ID NO: 16, but in which one or more of the loops are altered to bind to a target while the strains maintain their sequence as trunk portions, in which the loops are in residues 13-16, 22-28, 38-43, 51-54, 60-64 and 75-81 of SEQ ID NO: 16 and are capable of binding with cellular proteins and / or nucleic acid molecules.
