CC   -!- FUNCTION: Could be a determinant of virus virulence, since, when
CC       expressed in an otherwise attenuated JHM strain of murine coronavirus,
CC       it can dramatically increase the lethality of the latter. Seems to
CC       stimulate cellular DNA synthesis in vitro.
CC       {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}.
CC   -!- SIMILARITY: Belongs to the coronaviruses accessory protein 6 family.
