The invention relates to a protein construct, comprising (i) a targeting moiety that is capable of binding to a target cell, and (ii) an effector immunogenic moiety that is capable of triggering an existing, vaccine-induced or natural, immune response. The protein construct, that is preferably in the form of a heteromultimeric protein, is useful for redirecting an immune response that was pre-existing in a patient, toward an undesired target cell.

Protein constructs designed for targeting and lysis of cells

A method for preparing recombinant dimeric proteins using a nucleic acid coding for the C-terminal fragment of the C4BP protein &#x3b2; chain including amino acid residues 193 to 252 or a functional variant of the fragment, wherein the fragment enables covalent bonding of the heterologous polypeptides to which it is fused. Dimeric proteins obtained by means of the method and cells for carrying out the method are also described.

Recombinant dimeric and heterodimeric proteins comprising amino acids 193 to 252 of the &#x3b2; chain of the human C4BP protein
