Cathepsin B Function

Meaning

Cathepsin B Function describes the specific biological roles executed by the lysosomal cysteine protease Cathepsin B, a key enzyme in cellular homeostasis. Its primary function involves the controlled degradation of endogenous and exogenous proteins within the lysosome, essential for cellular waste disposal and nutrient recycling. Furthermore, Cathepsin B participates in critical non-lysosomal processes, including antigen presentation, pro-hormone processing, and the controlled initiation of certain cell death pathways. Proper function is integral to maintaining the delicate balance of protein turnover and overall cellular vitality, particularly in hormone-sensitive tissues.
