Cathepsin B belongs to family of lysosomal cysteine proteases and these are known to play vital functions during intracellular proteolysis. It can be synthesized on the rough endoplasmic reticulum as a pre-proenzyme that is 339 amino acid in length and it also possess a signal peptide that is 17 amino acids, this pro-cathepsin B of 43/46 kDa can then be transported to the Golgi apparatus where cathepsin B is formed.
