Bcl-2-like protein which targets host toll-like receptor signaling complexes to suppress innate immune response. Interacts with host TRAF6 to activate p38 and subsequently induce the expression of several cytokines such as IL-10. Associates also with host IRAK2 to inhibit NF-kappa-B signaling. Interacts with host TRAF6 and IRAK2. Belongs to the orthopoxvirus A52R protein family.
