Cathepsin F (CTSF) is a lysosomal cysteine protease expressed widely in tissues including brain, liver, and immune cells. CTSF belongs to the cathepsin family and has broad substrate specificity, allowing it to degrade various proteins within the lysosome. The enzyme is synthesized as a preproenzyme and processed to its active form in the lysosome. In the brain, CTSF is expressed in neurons and glial cells where it contributes to protein quality control and autophagy. CTSF has been implicated in neurodegenerative diseases including Alzheimer's and Parkinson's, where it may participate in the degradation of misfolded proteins. Mutations in CTSF cause a form of neuronal ceroid lipofuscinosis (CLN13), a group of lysosomal storage disorders characterized by progressive neurodegeneration, visual loss, and premature death. CTSF activity in neurons is essential for maintaining lysosomal function and cellular homeostasis.
Cathepsin F is a lysosomal cysteine protease expressed ubiquitously. It is one of the papain-like cathepsins and participates in protein degradation within lysosomes. Cathepsin F is highly expressed in neurons and is important for normal lysosomal function. Certain mutations cause a form of neuronal ceroid lipofuscinosis characterized by progressive neurodegeneration.
The CTSF gene is associated with several diseases.
The study of Ctsf 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.
