CC   -!- FUNCTION: Plays a role in the inhibition of the host NF-kappa-B
CC       pathway. This inhibition occurs at the receptor level, by preventing
CC       the signaling of TNFR1 as well as IL-1R and TLR3.
CC       {ECO:0000250|UniProtKB:P22112}.
CC   -!- SUBUNIT: Interacts with host TNFRSF1A, RIPK1 AND IRAK1; these
CC       interactions interfere with host NF-kappa-B activation at the level of
CC       receptor complexes (By similarity). Interacts with host protein UBQLN4
CC       (By similarity). {ECO:0000250|UniProtKB:P22110,
CC       ECO:0000250|UniProtKB:P22112}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250|UniProtKB:P22112};
CC       Single-pass membrane protein {ECO:0000250|UniProtKB:P22112}. Host cell
CC       membrane {ECO:0000250|UniProtKB:P22112}; Single-pass membrane protein
CC       {ECO:0000250|UniProtKB:P22112}.
CC   -!- SIMILARITY: Belongs to the rubulavirus small hydrophobic protein
CC       family. {ECO:0000305}.
