CC   -!- FUNCTION: Disrupts cell nuclear import complex formation by tethering
CC       karyopherin alpha 2 and karyopherin beta 1 to the membrane. Retention
CC       of import factors at the ER/Golgi membrane leads to a loss of transport
CC       into the nucleus. Thereby prevents STAT1 nuclear translocation in
CC       response to interferon signaling, thus blocking the expression of
CC       interferon stimulated genes (ISGs) that display multiple antiviral
CC       activities. {ECO:0000250|UniProtKB:P59634}.
CC   -!- SUBUNIT: Interacts with host KPNA2. May interact with nsp8. Interacts
CC       with protein ORF9b. {ECO:0000250|UniProtKB:P59634}.
CC   -!- SUBCELLULAR LOCATION: Host endoplasmic reticulum membrane
CC       {ECO:0000250|UniProtKB:P59634}. Host Golgi apparatus membrane
CC       {ECO:0000250|UniProtKB:P59634}. Host cytoplasm
CC       {ECO:0000250|UniProtKB:P59634}. Note=Localizes to virus-induced
CC       vesicular structures called double membrane vesicles.
CC       {ECO:0000250|UniProtKB:P59634}.
CC   -!- SIMILARITY: Belongs to the coronaviruses accessory protein 6 family.
CC       {ECO:0000305}.
