Anti-ATG4B

0.5 mg/ml with 0.1 mg/ml BSA (US sourced), 0.05% sodium azide. Autophagy is the cellular mechanism of degradation and turnover of unnecessary or dysfunctional cellular components. The unneeded components are engulfed in vesicles called autophagosomes, where they are broken down and recycled. The æautophagy-related geneÆ ATG4B is a regulator of autophagasome maturation. The microtubule-associated protein LC3-I is lipidated (called LC3-II in its lipidated state) and recruited to the autophagosomal membrane where it is of vital importance in the maturation of autophagosomes. ATG4B regulates LC3-II availability by modulating LC3-I lipidation. Protein function: Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Cleaves the C-terminal amino acid of ATG8 family proteins MAP1LC3, GABARAPL1, GABARAPL2 and GABARAP, to reveal a C-terminal glycine. Exposure of the glycine at the C- terminus is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is necessary for autophagy. Has also an activity of delipidating enzyme for the PE-conjugated forms. [The UniProt Consortium]
