CC   -!- FUNCTION: Plays a role in the inhibition of host innate immunity by
CC       inducing the degradation of key host factors required to activate
CC       interferon production such as IRF3, IRF5 or IRF7. Associates with
CC       components of cullin RING ligases (CRLs) including CUL1 or CUL3, which
CC       are essential multisubunit ubiquitination complexes, to modulate their
CC       activities. {ECO:0000255|HAMAP-Rule:MF_04088}.
CC   -!- SUBUNIT: Interacts (via C-terminus) with host IRF3; this interaction
CC       leads to IRF3 degradation. Interacts with host IRF7; this interaction
CC       leads to IRF7 degradation. Interacts with host CUL1 and CUL3.
CC       {ECO:0000255|HAMAP-Rule:MF_04088}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm, host cytoskeleton
CC       {ECO:0000255|HAMAP-Rule:MF_04088}.
CC   -!- DOMAIN: The integrity of the zinc-binding domain in NSP1 is important
CC       for degradation of host IRF3. {ECO:0000255|HAMAP-Rule:MF_04088}.
CC   -!- SIMILARITY: Belongs to the rotavirus NSP1 family. {ECO:0000255|HAMAP-
CC       Rule:MF_04088}.
