Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Cleaves the C-terminal amino acid of ATG8 family proteins 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. Preferred substrate is GABARAPL2 followed by MAP1LC3A and GABARAP. Has also an activity of delipidating enzyme for the PE-conjugated forms.

Application Notes

The stated application concentrations are suggested starting points. Titration of the ATG4A antibody may be required due to differences in protocols and secondary/substrate sensitivity.


Recombinant human protein was used as the immunogen for the ATG4A antibody.


Aliquot the ATG4A antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
