Cathepsin S Ctss Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Cathepsin S is a lysosomal cysteine protease encoded by the CTSS gene. It is a member of the papain family of proteases and is distinguished by its ability to remain active at neutral pH and be secreted extracellularly [1]. Cathepsin S plays important roles in antigen processing, extracellular matrix remodeling, and immune regulation. [1]
Cathepsin S has a typical cysteine protease structure: [2]
Cathepsin S is synthesized as a preproenzyme: [3]
Cathepsin S has broad substrate specificity: [4]
Unlike most lysosomal cathepsins, Cathepsin S can function extracellularly: [5]
In the immune system, Cathepsin S serves critical roles: [6]
Cathepsin S has complex roles in AD: [7]
Cathepsin S is a drug target for several conditions:
The study of Cathepsin S Ctss Protein 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.
