摘要：
A peptide that binds specifically to neuropilin-1 (NRP1) without binding to neuropilin-2 (NRP2) is provided. A fusion protein, a fusion antibody, small-molecule drug, a nanoparticle, or a liposome, which comprises the peptide, and a pharmaceutical composition for treating or preventing cancer or angiogenesis-related diseases, and a composition for diagnosing cancer or angiogenesis-related diseases are provided. A polynucleotide encoding the peptide that binds specifically to NRP1 and a method for screening the peptide that binds specifically to NRP1 are provided. An antibody heavy-chain constant region Fc-fused peptide binding specifically to NRP1 has the property of binding specifically to NRP1, and thus when it is administered in vivo, it accumulates selectively in tumor tissue, and widens the intercellular space between tumor-associated endothelial cells to promote its extravasation and increases its tumor tissue penetration.
