EC 3.4.22.1 Usage And Synthesis
UsesCathepsin B from human liver has been used:
  • as a positive control in the screening Cathepsin B inhibitor assay
  • in wall extension (expansin activity) assay
  • in microinjection human foreskin fibroblasts to test its effect on apoptosis induction

UsesCathepsin B is a lysosomal cysteine proteinase which hydrolyzes proteins with a broad specificity for peptide bonds. Cathepsin B may be a useful tool in Alzheimer′s research, as it may have a role in the natural defense against the disease . Cathepsin B may be used to cleave procaspase 1 and procaspase 11, and to induce apoptosis in digitonin-permeabilized cells.
General DescriptionCathepsin B gene is mapped to human chromosome 8p23.1. It is a lysosomal cysteine with 252 amino acids distributed in two chains and is homologous to rat liver sequence. It has disc shaped structure with two domains namely the left-hand ′L′ domain at the amino terminal and right hand ′R′ domain at the carboxyl-terminal.
Biochem/physiol ActionsCathepsin B displays an endopeptidase and peptidyl dipeptidase activities. It may be associated with the pathophysiology of tumors. Cathepsin B is also regarded as a prominent protease in Leishmaniasis. It is overactivated in muscular dystrophy, pulmonary emphysema, and bone resorption.
Purification MethodsCathepsin B is purified by affinity chromatography on the semicarbazone of Gly-Phe-glycinal-linked to Sepharose 4B, with elution by 2,2'-dipyridyl disulfide [Rich et al. Biochem J 235 731 1986, Methods Enzymol 80 551 1981].
