Background Information

ATG4, a member of the cysteine protease family, plays an important role in autophagy induction. ATG4 enzymes cleave the C-terminal amino acid of ATG8 family proteins to reveal a C-terminal glycine that is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes. ATG4A, which may be a target for cancer prevention and intervention, has been reported to be related to breast tumorigenesis, lung cancer, ovarian cancer, cervical cancer and gastric cancer.
