Interactioni
Subunit structurei
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.
