Abstract:
A recombinant protein drug includes a parent protein drug coupled with a modified kininogen-1 peptide. The modified kininogen-1 peptide has the sequence of SEQ ID NO:2 or a homolog having a sequence identity of 80% or higher. The parent protein drug is a bispecific antibody having a first targeting domain linked by a bridging domain with a second targeting domain. The modified kininogen-1 peptide is fused between the first targeting domain and the bridging domain, or between the bridging domain and the second targeting domain. A method for increasing the serum half-life of a protein drug includes constructing a fusion protein comprising the protein drug coupled with a modified kininogen-1 peptide.
