CC   -!- FUNCTION: Bcl-2-like protein which targets host toll-like receptor
CC       signaling complexes to suppress innate immune response. Interacts with
CC       host TRAF6 to activate p38 and subsequently induce the expression of
CC       several cytokines such as IL-10. Associates also with host IRAK2 to
CC       inhibit NF-kappa-B signaling (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with host TRAF6 and IRAK2. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the orthopoxvirus A52R protein family.
CC       {ECO:0000305}.
