Function

E0WXJ2_9FLAV Component of the viral RNA replication complex that functions in virion assembly and antagonizes the host immune response.[ARBA:ARBA00024317] Functions as a signal peptide for NS4B and is required for the interferon antagonism activity of the latter.[ARBA:ARBA00003504] Serine protease subunit NS2B: Required cofactor for the serine protease function of NS3.[PROSITE-ProRule:PRU00859]

Publication Abstract from PubMed

There are four closely-related dengue virus (DENV) serotypes. Infection with one serotype generates antibodies that may cross-react and enhance infection with other serotypes in a secondary infection. We demonstrated that DENV serotype 2 (DENV2)-specific human monoclonal antibody (HMAb) 2D22 is therapeutic in a mouse model of antibody-enhanced severe dengue disease. We determined the cryo-electron microscopy (cryo-EM) structures of HMAb 2D22 complexed with two different DENV2 strains. HMAb 2D22 binds across viral envelope (E) proteins in the dimeric structure, which probably blocks the E protein reorganization required for virus fusion. HMAb 2D22 "locks" two-thirds of or all dimers on the virus surface, depending on the strain, but neutralizes these DENV2 strains with equal potency. The epitope defined by HMAb 2D22 is a potential target for vaccines and therapeutics.
