S6K-STING interaction regulates cytosolic DNA–mediated activation of the transcription factor IRF3

Activation of the transcription factor IRF3 is a key event in antiviral responses. Lichty and colleagues show that recruitment of the mTOR downstream effector S6K1 to the STING-TBK1 signaling complex is required for the activation of IRF3 after infection with DNA viruses.
