Jc polyomavirus vlp (virus-like particle) with a targeting peptide

Abstract

The disclosure relates to a fusion protein comprising at least a first and a second peptide, wherein —the second peptide comprises a targeting region and a first and a second interaction region, —the second peptide is located on the surface of the fusion protein; —the second peptide comprises at least two interaction pairs, wherein an interaction pair is formed by an amino acid of the first interaction region and an amino acid of the second interaction region, —the interaction between the amino acids of an interaction pair is covalent or non-covalent; and —at least one interaction pair is a covalent interaction pair in which the amino acids are covalently bound, and to virus like particles (VLP) comprising the fusion protein for use as drug delivery system. Also provided are polynucleotides encoding the fusion protein, suitable expression vectors, host cells, production methods for the fusion protein and the VLP comprising the fusion protein.

Dependencies are inferred from the claim text.
