Modeling Of C-Terminal Tail Of Human Sting And Its Interaction With Tank-Binding Kinase 1, Rahaf Ata Ouda Al-Masri, Hajara Audu-Bida, Şebnem Eşsi̇z

Turkish Journal of Biology

Stimulator of interferon genes (STING) plays a significant role in a cell's intracellular defense against pathogens or self-DNA by inducing inflammation or apoptosis through a pathway known as cGAS-cGAMP-STING. STING uses one of its domains, the C-terminal tail (CTT) to recruit the members of the pathway. However, the structure of this domain has not been solved experimentally. STING conformation is open and more flexible when inactive. When STING gets activated by cGAMP, its conformation changes to a closed state covered by 4 beta-sheets over the binding site. This conformational change leads to its binding to Tank-binding kinase 1 (TBK1). TBK1 …
