|Other Names||Cysteine protease ATG4B, 3422-, AUT-like 1 cysteine endopeptidase, Autophagin-1, Autophagy-related cysteine endopeptidase 1, Autophagy-related protein 4 homolog B, hAPG4B, ATG4B, APG4B, AUTL1, KIAA0943|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Synonyms||APG4B, AUTL1, KIAA0943|
|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.|
|Tissue Location||Mainly expressed in the skeletal muscle, followed by brain, heart, liver and pancreas|

Autophagy is the process by which endogenous proteins anddamaged organelles are destroyed intracellularly. Autophagy ispostulated to be essential for cell homeostasis and cell remodelingduring differentiation, metamorphosis, non-apoptotic cell death,and aging. Reduced levels of autophagy have been described in somemalignant tumors, and a role for autophagy in controlling theunregulated cell growth linked to cancer has been proposed. Thisgene encodes a member of the autophagin protein family. The encodedprotein is also designated as a member of the C-54 family ofcysteine proteases. Alternate transcriptional splice variants,encoding different isoforms, have been characterized. [provided byRefSeq].
