The invention discloses a frame and a virus encoding bispecific molecules that secrete and mediate effector cells killing target cells. The recombinant protein provided by the present invention includes functional domain A and functional domain B; said functional domain A specifically binds to tumor-associated antigens or HLA polypeptide complexes on tumor cells; said functional domain B specifically binds to T cell surface markers or NK Cell surface markers. After the recombinant adenovirus provided by the present invention infects tumor cells, the tumor cells become factories for the expression of bispecific recombinant proteins, which can reduce the number of treatments compared with direct administration of fusion proteins. Introduce adenovirus into tumors by in situ injection , the expressed fusion protein can immediately bind to tumor cells without undergoing in vivo metabolism. Compared with direct injection of fusion protein, it is more efficient, and once there are effector cells around the tumor, it can be killed immediately. The invention has great value for tumor therapy.
