Function
Cysteine protease that plays a key role in autophagy by mediating both proteolytic activation and delipidation of ATG8 family proteins (PubMed:15169837, PubMed:15187094, PubMed:17347651, PubMed:19322194, PubMed:21177865, PubMed:22302004, PubMed:26378241, PubMed:27527864, PubMed:28633005, PubMed:28821708, PubMed:29232556, PubMed:30076329, PubMed:30443548, PubMed:30661429). Required for canonical autophagy (macroautophagy), non-canonical autophagy as well as for mitophagy (PubMed:33773106, PubMed:33909989). The protease activity is required for proteolytic activation of ATG8 family proteins: cleaves the C-terminal amino acid of ATG8 proteins MAP1LC3A, MAP1LC3B, MAP1LC3C, GABARAPL1, GABARAPL2 and GABARAP, to reveal a C-terminal glycine (PubMed:15169837, PubMed:15187094, PubMed:17347651, PubMed:19322194, PubMed:20818167, PubMed:21177865, PubMed:22302004, PubMed:27527864, PubMed:28287329, PubMed:28633005, PubMed:29458288, PubMed:30661429). Exposure of the glycine at the C-terminus is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is necessary for autophagy (PubMed:15169837, PubMed:15187094, PubMed:17347651, PubMed:19322194, PubMed:21177865, PubMed:22302004). Protease activity is also required to counteract formation of high-molecular weight conjugates of ATG8 proteins (ATG8ylation): acts as a deubiquitinating-like enzyme that removes ATG8 conjugated to other proteins, such as ATG3 (PubMed:31315929, PubMed:33773106). In addition to the protease activity, also mediates delipidation of ATG8 family proteins (PubMed:15187094, PubMed:19322194, PubMed:28633005, PubMed:29458288, PubMed:32686895, PubMed:33909989). Catalyzes delipidation of PE-conjugated forms of ATG8 proteins during macroautophagy (PubMed:15187094, PubMed:19322194, PubMed:29458288, PubMed:32686895, PubMed:33909989). Also involved in non-canonical autophagy, a parallel pathway involving conjugation of ATG8 proteins to single membranes at endolysosomal compartments, by catalyzing delipidation of ATG8 proteins conjugated to phosphatidylserine (PS) (PubMed:33909989). Compared to other members of the family (ATG4A, ATG4C or ATG4C), constitutes the major protein for proteolytic activation of ATG8 proteins, while it displays weaker delipidation activity than other ATG4 paralogs (PubMed:29458288, PubMed:30661429). Involved in phagophore growth during mitophagy independently of its protease activity and of ATG8 proteins: acts by regulating ATG9A trafficking to mitochondria and promoting phagophore-endoplasmic reticulum contacts during the lipid transfer phase of mitophagy (PubMed:33773106).

Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
ATG4B is a cysteine protease also known as autophagin-1 with a molecular mass of approximately 45 kDa. It is involved in the autophagy process by cleaving ATG8 family proteins. This protease facilitates the lipidation of LC3 an essential component of the autophagosome membrane. You find ATG4B expressed in various tissues especially in the brain liver and muscle where it plays important roles in cellular maintenance.
- Biological function summary
ATG4B functions in the cellular autophagic machinery cleaving the C-terminal of ATG8 proteins. This processing is necessary for the conjugation to phosphatidylethanolamine and integration into autophagosomes. ATG4B is part of a larger autophagic complex that also includes other critical proteins like ATG7 and ATG3 helping prepare ATG8 proteins for autophagosome creation.
- Pathways
ATG4B participates in the autophagy pathway by refining the cargo processing mechanism. It interacts with the mTOR signaling pathway which influences cell survival and growth based on nutrient availability. The ATG4B enzyme is closely related to ATG7 in the pathway as both contribute to the maturation of autophagosomes.
- Associated diseases and disorders
ATG4B has significant links to cancer and neurodegenerative disorders. In cancer ATG4B activity affects tumor survival since cancer cells exploit autophagy for growth under stress conditions. In neurodegenerative diseases like Alzheimer's alterations in ATG4B activity disrupt cellular homeostasis. This disruption connects to proteins like LC3 which are pivotal in neuron survival and function.
