Cathepsin L (CTSL) is a lysosomal cysteine protease that plays essential roles in protein degradation, extracellular matrix remodeling, and immune function. CTSL exhibits potent endopeptidase activity and can degrade a wide range of substrates including extracellular matrix proteins, growth factors, and viral proteins. The enzyme is synthesized as a preproenzyme and processed to its active form in the lysosome. In neurons, CTSL contributes to protein quality control by degrading misfolded proteins and aggregates through the autophagy-lysosome pathway. CTSL has been studied extensively in cancer where its upregulation in tumors promotes invasion and metastasis through extracellular matrix degradation. In neurodegenerative diseases, CTSL activity is generally considered protective as it contributes to clearance of amyloid-beta and alpha-synuclein aggregates, though dysregulation can contribute to pathological protein aggregation and neuronal dysfunction.
Cathepsin L is a lysosomal cysteine protease with broad substrate specificity. It degrades proteins in lysosomes and also processes antigens for MHC class II presentation. In neurodegeneration, cathepsin L may contribute to tau proteolysis and has been studied in the context of amyloid processing. It is implicated in various cancers and is a therapeutic target.
The CTSL gene is associated with several diseases.
The study of Ctsl Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
