Abstract

A fusion nanoprotein is provided wherein TRAIL with a trimer structure is conjugated to a human ferritin monomer fragment and exhibits enhanced cancer targeting using a cancer-targeting peptide. The fusion protein effectively targets cancer cells when injected into a blood vessel, leading to TRAIL-induced cancer cell death. This fusion nanoprotein addresses key challenges of TRAIL proteins by improving their stability and reducing off-target effects through stable delivery of TRAIL trimers specifically to cancer tissues. The enhanced stability and targeted delivery properties make this fusion protein a promising candidate for development as an anticancer therapeutic agent.
