ATG4B, also known as cysteine protease ATG4B, is a 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.
Source:Recombinant corresponding to aa1-393 from human ATG4B, fused to His-tag at C-terminus, expressed in E.coli.
Molecular Weight:~45.4kD (401aa) confirmed by MALDI-TOF
Enzyme Activity:Not determined. This product is recommended for use in applications that do not require a catalytically active form of the protein.
