Background

Japanese encephalitis virus (JEV) non-structural protein 1 (NS1) is produced by the Japanese encephalitis virus (JEV), a mosquito-borne flavivirus that is the leading cause of virus-induced encephalitis globally (1). Flavivirus NS1 is a multifunctional virulence factor. The glycosylated NS1 exists as a membrane-associated dimer after translocation into the endoplasmic reticulum lumen, where it is essential for viral genome replication (2). The secreted hexamer NS1 is involved in immune evasion and pathogenesis; it is identified as a potential diagnostic marker for early detection of the virus infections (2). Mature viral JEV NS1 contains 352 amino acids and shares high structural similarity to other flavivirus NS1 proteins, such as DENV and ZIKV.
