Background: Flavivirus group antigen

Flaviviruses are a group of seventy enveloped, positive-sense single stranded RNA viruses belonging to the Flaviviridae family (1-5). Flaviviruses are typically transmitted through arthropods, like mosquitoes and ticks, and can infect humans causing outbreaks and serious illness or death worldwide (1-5). These well-known viral pathogens include dengue virus (DENV), West Nile virus (WNV), Japanese encephalitis virus (JEV), tick-borne encephalitis virus (TBEV), Yellow Fever virus (YFV), and Zika virus (ZIKV) (1-5). Flaviviruses consist of ~10.7 kb RNA genome with one open reading frame (ORF) that is flanked by 5' and 3' untranslated regions (UTRs) (1, 2, 6). The ORF encodes for a polyprotein that is made up of three structural proteins, the capsid (C), premembrane (prM), and envelope (E) proteins, and seven non-structural (NS) proteins (NS1, NS2A/B, NS3, NS4A, 2K, NS4B, and NS5) (1, 2, 5, 6).

The Flavivirus group antigen antibody binds to the fusion loop at the distal end of domain II (EDII) of protein E. Flavivirus E is a glycoprotein that is the main antigen for membrane fusion between virus and host and entry into the cell, as well as inducing protective immunity by stimulating neutralizing antibodies (2, 4, 6). The E protein is 495 amino acids (aa) in length and has a theoretical molecular weight between 55 - 72 kDa, which varies based on glycosylation sites (2). Flavivirus E protein contains three domains (EDI, EDII, and EDIII) followed by a stem that contents to the helix-transmembrane domains (TMDs, TM1 and TM2) (2, 4, 6). The EDII contains an S-S bridge at its distal end and functions as a fusion loop (FL) for virus-mediated membrane fusion and antibody binding (2). Given the important role of Flavivirus protein E in host cell infection and membrane fusion, it has become a target for flavivirus disease prevention and treatment (2, 5).

Alternative names for Flavivirus group antigen include Envelope Protein and Protein E.
