Japanese Encephalitis Virus (JEV)
Structure and Key Research Targets

Japanese Encephalitis Virus (JEV) structure
Overview
Japanese encephalitis virus (JEV) is an enveloped, positive-sense single-stranded RNA virus belonging to the genus Flavivirus within the family Flaviviridae. JEV infection primarily affects the central nervous system and is an important model for studying flavivirus structure, viral replication, immune recognition, and antibody responses. The Envelope protein (E) is a major surface antigen involved in viral entry and neutralizing antibody recognition, making it a key target for JEV research.
JEV Structure
JEV is an approximately 40-50 nm enveloped virus containing an approximately 11 kb positive-sense single-stranded RNA genome. The viral surface is mainly composed of E and M proteins arranged on the lipid envelope. The E protein forms the outer protein shell and plays essential roles in receptor binding and membrane fusion during viral entry. The internal nucleocapsid contains viral RNA associated with the capsid protein, while non-structural proteins participate in viral RNA replication and polyprotein processing.
The viral genome encodes a single polyprotein that is processed into three structural proteins and seven non-structural proteins:
- Structural proteins: Capsid (C) protein, Premembrane/Membrane (prM/M) protein, Envelope (E) protein
- Non-structural proteins: NS1, NS2A, NS2B, NS3, NS4A, NS4B, NS5
