Mutant p53 (mtp53) proteins can exert cancer-promoting gain-of-function activities. We report a mechanism by which mtp53 suppresses both cell-autonomous and non-cell autonomous signaling to promote cancer cell survival and evasion of tumor immune surveillance. Mtp53 interferes with the function of the cytoplasmic DNA sensing machinery, cGAS-STING-TBK1-IRF3, that activates the innate immune response. Mtp53, but not wildtype p53, binds to TANK binding protein kinase 1 (TBK1) and prevents the formation of a trimeric complex between TBK1-STING-IRF3, which is required for activation, nuclear translocation and transcriptional activity of IRF3. Inactivation of innate immune signaling by mtp53 alters cytokine production resulting in immune evasion. Restoring TBK1 signaling is sufficient to bypass mtp53 and lead to restored immune cell function and cancer cell eradication. This work is of translational interest since therapeutic approaches that restore TBK1 function could potentially reactivate immune-surveillance and eliminate mtp53 tumors. Ghosh et al. show that mutant p53 suppresses downstream signaling from the cGAS/STING cytosolic DNA sensing pathway by interacting with TANK binding protein kinase 1 (TBK1), resulting in the attenuation of type I interferon response and the promotion of tumor growth through immune evasion.
