WebOct 1, 2000 · Cysteine protease that plays a key role in autophagy by mediating both proteolytic activation and delipidation of ATG8 family proteins. The protease activity is required for proteolytic activation of ATG8 family proteins: cleaves the C-terminal amino acid of ATG8 proteins to reveal a C-terminal glycine (By similarity). Exposure of the glycine at … WebSep 2, 2024 · ATG4B, a cysteine protease promoting autophagosome formation by reversibly modifying Atg8-family proteins, plays a vital role in controlling macroautophagy/autophagy initiation in response to stress. However, the molecular mechanism underlying the regulation of ATG4B activity is far from well elucidated. In the …
WebIt rarely inhibits other cysteine proteases, aspartate proteases or serine proteases. Interestingly, S130 could also inhibit ATG4A in vitro owing to its high degree of similarity to protein structures of ATG4A and ATG4B; hence S130 might be the first potent inhibitor studied that has dual inhibition of ATG4B and ATG4A. WebLC3 is a substrate of the cysteine protease ATG4B (Autophagin-1), where cleavage generates a C-terminal glycine required for LC3 conjugation to lipids in autophagosomes. ATG4B both cleaves pro-LC3 and also …
