CC   -!- FUNCTION: Suppresses the host immune response through NF-kappa-B
CC       inactivation. Possesses ankyrin repeat domain required for NF-kappa-B
CC       binding but lack the regulatory regions required for dissociation from
CC       NF-kappa-B and degradation. Therefore, prevents host NF-kappa-B release
CC       and subsequent activation (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the polydnaviridae I-Kappa-B-like protein
CC       family. {ECO:0000305}.
