Stimulator of interferon genes protein (STING)

Target
STING
Molecular classification
Adaptor protein, Transmembrane protein
01

Overview

STING is a critical adaptor protein in the innate immune system that acts as a cytosolic DNA sensor and triggers type I interferon production. Upon detection of cytosolic DNA or binding of cyclic dinucleotides (CDNs), STING undergoes conformational changes, translocates to perinuclear compartments, recruits TBK1 kinase, and activates IRF3, leading to the expression of interferon-stimulated genes. STING plays a role in antiviral defense, cancer immunity, and inflammatory responses, making it a therapeutic target for infectious diseases, cancer immunotherapy, and inflammatory disorders. Pharmacological modulation of STING, using both agonists and inhibitors, is under investigation for clinical use.
