"Homomultimerizes to form the nucleocapsid. Binds to viral genomic RNA. Interacts with glycoprotein G2. Interacts with protein Z; this interaction probably directs the encapsidated genome to budding sites. Interacts with protein L; this interaction does not interfere with Z-L interaction. Interacts with host IKBKE (via Protein kinase domain); the interaction inhibits IKBKE kinase activity."xsd:string
