Function Cysteine protease ATG4D: Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Cleaves the C-terminal amino acid of ATG8 family proteins MAP1LC3 and GABARAPL2, to reveal a C-terminal glycine. 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. Has also an activity of delipidating enzyme for the PE-conjugated forms (By similarity). {ECO:0000250}.Cysteine protease ATG4D, mitochondrial: Plays a role as an autophagy regulator that links mitochondrial dysfunction with apoptosis. The mitochondrial import of ATG4D during cellular stress and differentiation may play important roles in the regulation of mitochondrial physiology, ROS, mitophagy and cell viability (By similarity). {ECO:0000250}.
Subcellular Localization Cysteine protease ATG4D: Cytoplasm {ECO:0000250}.Cysteine protease ATG4D, mitochondrial: Cytoplasm. Mitochondrion matrix {ECO:0000250}. Note=Imported into mitochondrial matrix after cleavage by CASP3 during oxidative stress and cell death. {ECO:0000250}.
