Protein attributes

Sequence length	458 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Cysteine protease required for autophagy, which cleaves the C-terminal part of either MAP1LC3, GABARAPL2 or GABARAP, allowing the liberation of form I. A subpopulation of form I is subsequently converted to a smaller form (form II). Form II, with a revealed C-terminal glycine, is considered to be the phosphatidylethanolamine (PE)-conjugated form, and has the capacity for the binding to autophagosomes By similarity.
Enzyme regulation	Inhibited by N-ethylmaleimide By similarity.
Subcellular location	Cytoplasm Probable.
Sequence similarities	Belongs to the peptidase C54 family.
