  • 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.
  • Tissue specificity

    Mainly expressed in skeletal muscle and, to a lower extent, in testis.
  • Sequence similarities

    Belongs to the peptidase C54 family.
  • Cellular localization
