CTSZ (Cathepsin Z), also known as Cathepsin X, is a unique lysosomal cysteine protease that possesses both endopeptidase and carboxypeptidase activities[1]. Unlike other cathepsins, CTSZ contains an extended proline-rich region and a unique C-terminal tail that mediates its distinctive functions[2]. It is widely expressed across tissues with particularly high levels in immune cells, brain, and various epithelial surfaces.
CTSZ exhibits unique catalytic properties:
CTSZ is expressed in:
CTSZ involvement in AD includes[3]:
In PD, CTSZ contributes to:
CTSZ is a potential therapeutic target:
The study of Ctsz Gene Cathepsin Z 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.
