Viral TLR3 homolog that probably prevents TLR3 dimerization and subsequent induction of IFN. Inhibits dsRNA-stimulated activation of NF-kB and IRF3. Contains putative leucine-rich repeats (LRR) and a C-terminus cysteine-rich capping motif similar to domain structure of host TLR3. Highly glycosylated. Belongs to the asfivirus I329L family.
