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. |
Subcellular Location | Cysteine protease ATG4D: Cytoplasm. |
Tissue Specificity | Mainly expressed in skeletal muscle and, to a lower extent, in testis. {ECO:0000269|PubMed:12446702}. |
