Antibody-Drug Conjugate (ADC) Target Proteins
Non-secretory:The target antigen should be non-secretory to avoid excessive secretion of antigens causing non-specific binding of antigen-antibody complexes in circulation, which would lead to non-specific binding of ADCs outside the tumor site, thereby reducing drug targeting and potentially increasing safety risks[2].
Internalization Properties:After binding with antibody, the target antigen should be able to effectively internalize into tumor cells, ensuring that ADC complexes enter cells through endocytosis, and then promote rapid release of cytotoxic payloads through appropriate intracellular transport pathways[3] to exert anti-tumor effects.
