||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. ENZYME REGULATION: Inhibited by N-ethylmaleimide. SUBCELLULAR LOCATION: Cytoplasm (Probable). ALTERNATIVE PRODUCTS: 5 named isoforms produced by alternative splicing. TISSUE SPECIFICITY: Mainly expressed in the skeletal muscle, followed by brain, heart, liver and pancreas. SIMILARITY: Belongs to the peptidase C54 family.

||IHC, immunofluorescence, WB. A dilution of 1:100 to 1:2000 dilution is recommended for these applications. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
||IHC, WB and ELISA confirmed the specificity for ATG4B.
||Human, rat. Other species not yet tested.
||Reconstitute in 100 µl of sterile water. Centrifuge to remove any insoluble material.
||After reconstitution keep aliquots at -20ºC for a higher stability, and at 4ºC with an appropriate antibacterial agent. Glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles.
