Sqstm1 P62 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.
SQSTM1 (Sequestosome-1), commonly known as p62, is a multifunctional autophagy adapter protein involved in protein degradation, signaling, and neurodegeneration. Mutations cause Paget disease of bone and are associated with ALS/FTD.

This page provides comprehensive information about p62/SQSTM1, including its structure, normal function in the nervous system, and its role in neurodegenerative diseases.
SQSTM1 is a 440 amino acid scaffold protein with multiple domains:
p62/SQSTM1 is a master regulator of cellular homeostasis:
SQSTM1 mutations cause ALS/FTD:
| Strategy | Status | Notes |
|---|---|---|
| Autophagy enhancers | Research | Increase p62 function |
| Nrf2 activators | Clinical trials | Protective pathway |
| Gene therapy | Preclinical | Restore function |
| Small molecules | Discovery | Target protein interactions |
SQSTM1/p62 is a critical autophagy adapter protein that connects ubiquitin-tagged cargo to the autophagic machinery. Its role in neurodegenerative diseases makes it an important therapeutic target. Strategies to enhance p62 function or restore its activity may provide benefit in ALS, FTD, AD, and PD.
The study of Sqstm1 P62 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.
