| Post Translational Modifications | Phosphorylated by TBK1. Following activation, phosphorylated by TBK1 at Ser-210 in the pLxIS motif. The phosphorylated pLxIS motif constitutes an IRF3-binding motif, leading to recruitment of the transcription factor IRF3 to induce type-I interferons and other cytokines. Polyubiquitinated at Lys-229 by TRIM38 with 'Lys-48'-linked chains, leading to proteasomal degradation. Polyubiquitinated with 'Lys-6'- and 'Lys-33'-linked chains in a TRIM8-dependent manner.ubiquitination disrupts the interaction with TBK1 and subsequent interferon production. (Microbial infection) Cleaved and degraded by hepatitis A virus (HAV) protein 3CD allowing the virus to disrupt host TLR3 signaling. (Microbial infection) Cleaved by CVB3 protease 3C allowing the virus to disrupt host TLR3 signaling. (Microbial infection) Cleaved by Seneca Valley virus protease 3C allowing the virus to disrupt host TLR3 signaling. (Microbial infection) Cleaved by protease 3C of human enterovirus D68 (EV68) allowing the virus to disrupt host TLR3 signaling. (Microbial infection) Cleaved by HCV protease NS3/4A, thereby disrupting TLR3 signaling and preventing the establishment of an antiviral state. |
| Function | Involved in innate immunity against invading pathogens. Adapter used by TLR3, TLR4 (through TICAM2) and TLR5 to mediate NF-kappa-B and interferon-regulatory factor (IRF) activation, and to induce apoptosis. Ligand binding to these receptors results in TRIF recruitment through its TIR domain. Distinct protein-interaction motifs allow recruitment of the effector proteins TBK1, TRAF6 and RIPK1, which in turn, lead to the activation of transcription factors IRF3 and IRF7, NF-kappa-B and FADD respectively. Phosphorylation by TBK1 on the pLxIS motif leads to recruitment and subsequent activation of the transcription factor IRF3 to induce expression of type I interferon and exert a potent immunity against invading pathogens. Component of a multi-helicase-TICAM1 complex that acts as a cytoplasmic sensor of viral double-stranded RNA (dsRNA) and plays a role in the activation of a cascade of antiviral responses including the induction of pro-inflammatory cytokines. |
