Belongs to the betacoronaviruses M protein family.
Component of the viral envelope that plays a central role in virus morphogenesis and assembly via its interactions with other viral proteins.
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.

Lacks conserved residue(s) required for the propagation of feature annotation.
Belongs to the betacoronaviruses E protein family.
Homopentamer. Interacts with membrane protein M in the budding compartment of the host cell, which is located between endoplasmic reticulum and the Golgi complex. Interacts with Nucleoprotein.
Plays a central role in virus morphogenesis and assembly. Acts as a viroporin and self-assembles in host membranes forming pentameric protein-lipid pores that allow ion transport. Also plays a role in the induction of apoptosis.
