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:0000255|HAMAP-Rule:MF_04202, ECO:0000255|PROSITE-
CC       ProRule:PRU01275}.
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.

CC       ProRule:PRU01275}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000255|HAMAP-
CC       Rule:MF_04202}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_04202}. Host Golgi apparatus membrane {ECO:0000255|HAMAP-
CC       Rule:MF_04202}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_04202}. Note=Largely embedded in the lipid bilayer.
CC       {ECO:0000255|HAMAP-Rule:MF_04202}.
CC   -!- SIMILARITY: Belongs to the betacoronaviruses M protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04202}.
