ATG4B(autophagy 4) is also named as APG4B, AUTL1, KIAA0943 and belongs to the peptidase C54 family. It is a homolog of yeast Apg4, a cysteine protease involved in autophagy and is a cytoplasmic enzyme. This protein is highly expressed in skeletal muscle, with lower expression in heart, liver, and pancreas and no expression is detected in fetal tissues by the northern blot. ATG4B is widely expressed in tumor cell lines (PMID:12446702). It has some isoforms produced by alternative splicing with molecular mass of 31-52 kDa.
