Comments [?]

Function Component of the viral envelope that plays a central role in virus morphogenesis and assembly via its interactions with other viral proteins.
Subunit Homomultimer. Interacts with envelope E protein in the budding compartment of the host cell, which is located between endoplasmic reticulum and the Golgi complex. Forms a complex with HE and S proteins. Interacts with nucleocapsid N protein. This interaction probably participates in RNA packaging into the virus.
Subcellular location Virion membrane; Multi-pass membrane protein. Host Golgi apparatus membrane; Multi-pass membrane protein. Note=Largely embedded in the lipid bilayer.
Similarity Belongs to the betacoronaviruses M protein family.
