Summary

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.

Similarity

Belongs to the gammacoronaviruses M protein family.
