CLPP is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of CLPP is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
CLPP is a mitochondrial matrix protease involved in protein quality control:
- Protein degradation: Cleaves misfolded and damaged proteins
- Mitochondrial protein homeostasis: Essential for mitochondrial proteostasis
- RNA metabolism: Processes mitochondrial RNAs
- Stress response: Activated under mitochondrial stress
- CLPP mutations cause Perrault syndrome (hearing loss + ovarian dysfunction)
- May have neurological manifestations
- Implicated in mitochondrial dysfunction in various neurodegenerative diseases
- Related to mitochondrial protein aggregate clearance
- Ubiquitously expressed
- High levels in tissues with high mitochondrial content

The study of Clpp (Caseinolytic Mitochondrial Matrix Peptidase Proteolytic) 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.
