A chimeric carrier protein having a multimerization domain and at least one drug attached thereto via a spacer is disclosed. The protein may be targeted by associating at least one amino acid sequence having an amino acid domain targeted to a specific site of action. In a further embodiment of the invention a nucleic acid molecule is provided which encodes the protein. Vectors containing the nucleic acid molecule and the host cells containing the vectors may also be provided. A method for producing the carrier chimeric protein on the targeted carrier chimeric protein is also disclosed.
