Apg4a, ATG4A, Atg4al, AUT like 2 cysteine endopeptidase, Autl2, Autophagin 2, Autophagin-2, Autophagy related 4A cysteine peptidase.
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.
