Glycoprotein C and glycoprotein N interact with each other and are present at the surface of the virion. They are able to attach the virion to a cell receptor and to promote fusion of membranes after endocytosis of the virion (By similarity). Glycoprotein C and Glycoprotein N interact with each other. Interaction between Glycoprotein C and Glycoprotein N is essential for proper targeting of Glycoprotein C to the Golgi complex, where virion budding occurs. Specific enzymatic cleavages in vivo yield mature proteins including Glycoprotein C and Glycoprotein N. Belongs to the nairovirus envelope glycoprotein family.
