ATG4B - a cysteine protease involved in autophagosome elongation

Autophagy can be broken down into 4 main stages: phagophore nucleation, autophagosome elongation, autophagosome docking and fusion with a lysosome, and vesicle breakdown and degradation. ATG4B is one of four ATG4 homologs (ATG4A, ATG4B, ATG4C, and ATG4D) involved in autophagosome elongation. ATG4B encodes a 48 kDa protein called autophagin-1 that is a member of the C54 family of cysteine proteases.
