FURIN and neoplasm: In this study, we engineered BumPeD, a novel bispecific nanobody‐targeted PROTACs‐like platform, by fusing two nanobodies with a Furin protease cleavage site (RVRR) and a degron sequence (ALAPYIP or KIGLGRQKPPKATK), enabling the tumor microenvironment to direct the degradation of intracellular proteins.
