Abstract: Pathogen-associated molecular pattern (PAMP) recognition leads to TANK-binding kinase (TBK1) polyubiquitination and activation by trans-autophosphorylation, resulting in IFN-β production. Here we describe a mouse model of optineurin insufficiency (OptnΔ157) in which the TBK1-interacting N-terminus of optineurin was deleted. PAMP-stimulated cells from OptnΔ157 mice had reduced TBK1 activity, no phosphorylation of optineurin Ser187, and mounted low IFN-β responses. In contrast to pull-down assays where the pres…
