Sestrin-3 (Sesn3)

May function as an intracellular leucine sensor that negatively regulates the TORC1 signaling pathway (PubMed:25259925). May also regulate the insulin-receptor signaling pathway through activation of TORC2 (PubMed:25377878).

This metabolic regulator may also play a role in protection against oxidative and genotoxic stresses (By similarity). .
