Anti-Autophagy related 4B cysteine peptidase antibodies are available from several suppliers. In humans, this protein is encoded by the gene ATG4B. The protein may also be known as ATG4 autophagy related 4 homolog B, APG4B, AUTL1, and cysteine protease ATG4B. The expected protein mass is 44.3 kDa, but there are 5 reported isoforms. Variants of this antigen may also be found in other species, including fly, canine, porcine, monkey, mouse and rat.
