Figure 2. Diagram of the flavivirus virion. An icosahedral nucleocapsid (half shown here) encloses the virion RNA. The virion has an envelope derived from the host cell membranes. E-glycoprotein (E), an integral membrane protein, is arranged as homodimers (head-to-tail) and associates with the other integral membrane proteins prM protein (in immature virions).
