    • 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 noncovalent; 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.
    • 本公开涉及包含至少第一和第二肽的融合蛋白,其中 - 第二肽包含靶向区和第一和第二相互作用区, - 第二肽位于融合蛋白的表面上; - 第二肽包含至少两个相互作用对,其中相互作用对由第一相互作用区的氨基酸和第二相互作用区的氨基酸形成, - 相互作用对的氨基酸之间的相互作用是共价键或 非共价的; 和 - 至少一个相互作用对是其中氨基酸共价结合的共价相互作用对,并且是包含用作药物递送系统的融合蛋白的病毒样颗粒(VLP)。 还提供了编码融合蛋白的多核苷酸,合适的表达载体,宿主细胞,融合蛋白的生产方法和包含融合蛋白的VLP。
