Endogenous inhibitors of lysosomal proteinases.
Specific inhibitors of three lysosomal proteinases are present in the cytosolic and lysosomal compartments of rabbit liver. The cytosolic inhibitors, purified by chromatography on DEAE-Trisacryl and Sephadex G-75, show specificities toward cathepsin M, cathepsins B and L, and fructose 1,6-bisphosphatase converting enzyme (CE), respectively, and are designated IM, IB/L, and ICE. Inhibitors with ...

Limited proteolysis of liver aldolase and fructose 1,6-bisphosphatase by lysosomal proteinases: effect on complex formation.
Cathepsin M, which catalyzes inactivation of both rabbit liver fructose-1,6-bisphosphate aldolase (EC 4.1.2.13) and rabbit liver fructose 1,6-bisphosphatase (Fru-P2ase; EC 3.1.3.11), has been characterized as a peptidyl peptidase. Modification of the COOH terminus of aldolase by cathepsin M or by Fru-P2ase converting enzyme 2 abolishes its ability to bind to phosphocellulose P11 and to form the...
متن کاملImmunocytochemical localization of lysosomal cysteine and aspartic proteinases, and ubiquitin in rat epidermis.
To analyze the degradation system in epidermal cells during their generation, differentiation, and cell death, immunocytochemical localization of lysosomal cysteine and aspartic proteinases, an endogenous cysteine proteinase inhibitor, cystatin beta, and ubiquitin were examined using rat sole skin. By confocal laser microscopy, granular immunodeposits for lysosomal proteinases were well demonst...
متن کاملInvolvement of Lysosomal Labilisation and Lysosomal/mitochondrial Cross-Talk in Diclofenac Induced Hepatotoxicity
In this research, we investigated the cytotoxic mechanisms of one of the widely used pharmaceuticals that are regularly associated with the adverse effects on the liver, sometimes leading to acute liver failure, diclofenac. Diclofenac liver cytotoxicity was associated with reactive oxygen species (ROS) formation and lipid peroxidation which were inhibited by antioxidants and ROS scavengers, fer...
