Senp1 — Sumo Specific Peptidase 1 plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
SENP1 (SUMO Specific Peptidase 1) is a cysteine protease that catalyzes deSUMOylation—the removal of SUMO (Small Ubiquitin-Like Modifier) proteins from target substrates. As a key regulator of the SUMOylation cycle, SENP1 plays critical roles in cellular homeostasis, stress responses, transcription regulation, and protein quality control. Dysregulation of SENP1 is implicated in neurodegenerative diseases, cancer, and metabolic disorders. This page provides comprehensive information about SENP1's structure, function, and role in neurodegeneration.
