RT   viruses: the torovirus E protein.";
RL   Virology 182:655-663(1991).
CC   -!- FUNCTION: Component of the viral envelope that plays a central role in
CC       virus morphogenesis and assembly via its interactions with other viral
CC       proteins. {ECO:0000250}.
CC   -!- SUBUNIT: Homomultimer. Interacts with envelope E protein in the budding
CC       compartment of the host cell, which is located between endoplasmic
CC       reticulum and the Golgi complex. Forms a complex with HE and S
CC       proteins. Interacts with nucleocapsid N protein. This interaction
CC       probably participates in RNA packaging into the virus (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}. Host Golgi apparatus membrane
CC       {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}. Note=Largely
CC       embedded in the lipid bilayer. {ECO:0000250}.
