Patent ID: 7811805

Claim:
A chimera protein, wherein a peptide capable of binding specifically to a desired cell surface molecule is joined, directly or via a peptide linker, to the N-terminus side of the transmembrane domain of F protein derived from a paramyxovirus consisting of the amino acid sequence shown by SEQ ID NO: 11 or an amino acid sequence having a homology of 90% or more thereto and having an activity mediating fusion of the paramyxovirus and the cell, wherein the desired cell surface molecule is selected from a group consisting of desmoglein 3, β2 integrin, α4 integrin, αIIbβ3 integrin, folic acid receptor, transferrin receptor, HER2, epidermal growth factor receptor (EGFR), Low-density lipoprotein receptor (LDLR), CD20, carcinoembryonic antigen (CEA), glycoprotein 100 (Gp100), Prostate Specific Membrane Antigen (PSMA), and α-fetoprotein (AFP).
