|Other Names||Cysteine protease ATG4D, 3422-, AUT-like 4 cysteine endopeptidase, Autophagin-4, Autophagy-related cysteine endopeptidase 4, Autophagy-related protein 4 homolog D, Cysteine protease ATG4D, mitochondrial, ATG4D, APG4D, AUTL4|
|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.|
|Function||Cysteine protease ATG4D: Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Cleaves the C-terminal amino acid of ATG8 family proteins MAP1LC3 and GABARAPL2, 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.|
|Cellular Location||Cysteine protease ATG4D: Cytoplasm.|
|Tissue Location||Mainly expressed in skeletal muscle and, to a lower extent, in testis.|

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.
