Listed are ELISA Kits for the detection of APG4D, an alias name of autophagy related 4D cysteine peptidase. The human protein, encoded by the gene ATG4D, is 474 amino acid residues long and has a mass of 52,922 daltons. However, there are up to 2 reported isoforms. It is an enzyme of the peptidase (broad) class and is a member of the Peptidase C54 family. This protein is reported to have a cytoplasmic and mitochondrial cellular localization. This target may also be known as: cysteine protease ATG4D, APG4 autophagy 4 homolog D, ATG4 autophagy related 4 homolog D, AUT-like 4 cysteine endopeptidase, autophagy-related cysteine endopeptidase 4, autophagy-related protein 4 homolog D, and cysteine protease involved in autophagy.
