The mutational landscape of STING-induced immunity

Listed in NCBI GEO

Stimulator of interferon genes (STING) is an evolutionary conserved immune signalling protein with key roles in host defence, cancer, senescence and inflammation.STING activation leads to type I interferon (IFN), NF-κB pathway and non-canonical autophagy responses.

Description

Despite its central role in immunity and relevance as therapeutic target, the sequence elements that govern STING (in)activation in cells remain poorly understood.

Here we developed a massively parallel assay to systematically chart the sequence-function landscape of STING. Profiling thousands of single amino-acid variants, we reconstructed structural and functional determinants that moderate or enable, respectively, STING’s immunostimulatory capacity and its ability to translate ligand recognition into cellular effector responses. Cryo-electron microscopy structures of distinct STING hyperactive variants revealed novel regulatory principles dictating conformational transition from inactive to signalling-competent states of STING.

Collectively, these findings define the molecular principles that tune STING activity and chart the full landscape of its functional potential across immune contexts.
