MUTATED HUMAN 2IG-B7-H3 PROTEIN CODING GENE, RECOMBINANT VECTOR, HOST CELL CONTAINING SAME, PHARMACEUTICAL COMPOSITION AND APPLICATION THEREOF

摘要

The present disclosure relates to the field of genetic engineering, in particular to a mutant human 2Ig-B7-H3 protein encoding gene, a protein, a recombinant vector, and a pharmaceutical composition including the gene or protein. The regulatory expression, interaction and signal transmission of the protein encoded by the gene of the present disclosure play an extremely important role in the tumor immune response process, and especially provide a new and beneficial way for the prevention and treatment of cancer.
