Autophagy-related 4B (ATG4B), also known as autophagin-1, is a cysteine protEAse and a member of the C54 protEAse family with dual roles in the progression of autophagy.1,2 It catalyzes the irreversible proteolytic clEAvage of human homologs of yEAst atg8 belonging to the microtubule-associated proteins 1 (MAP1)A/B-light chain 3 (LC3) and the GABA receptor-associated protein (GABARAP) subfamilies, including LC3, GATE16, GABARAP, and ATG8L, to expose a C-terminal glycine residue that is essential to formation of the autophagosome. It also catalyzes the reversible deconjugation of phosphatidylethanolamine from C-terminal glycine lipid-conjugated atg8 homologs.3 ATG4B expression is incrEAsed in CD34+ chronic myeloid leukemia (CML) stem and progenitor cells and knockdown of ATG4B expression incrEAses accumulation of LC3-II and p62, indicating impaired autophagy, and reduces the viability and inhibits proliferation of CD34+ CML cells.4 Atg4-/- mice exhibit systemic decrEAses in basal and induced autophagy as well as incrEAsed susceptibility to colitis induced by dextran sodium sulfate (DSS) and pulmonary fibrosis induced by bleomycin (Item No. 13877).5,6 Technical Information Synonyms AUT-like 1 Cysteine Endopeptidase Autophagin-1 Autophagy-related 4B Cysteine Peptidase Autophagy-related Protein 4 Homolog B hAPG4B Purity 80% estimated by SDS-PAGE Source Recombinant N-terminal histidine-tagged ATG4B purified from E. coli Amino Acids 2-393 MW 43.4 kDa Formulation 50 mM HEPES, pH 8.0, 150 mM sodium chloride, 10% glycerol UniProt Accession Q9Y4P1
