Sesn1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
SESN1 (Sestrin 1) is a stress-responsive protein that plays critical roles in cellular homeostasis, antioxidant defense, and metabolic regulation. It is one of three mammalian sestrins (SESN1, SESN2, SESN3) that are induced by various stress conditions including oxidative stress, DNA damage, and hypoxia. Sestrins are emerging as important protective factors in neurodegeneration through their regulation of mTOR signaling and AMPK activation.
SESN1 performs several critical cellular functions:
SESN1 may be protective in AD:
SESN1 protects dopaminergic neurons:
