Descripción

General description

Genome polyprotein (UniProt: P14335) is encoded by the POLY gene (Gene ID: 912267) in West Nile virus. West Nile virus (WNV) is a mosquito-borne positive-sense RNA virus of the Flavivirus genus within the Flaviviridae family. WNV genome encodes for three structural domains known as C, prM, and E and seven non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). These are translated as a single polypeptide, which is subsequently cleaved by viral and cellular proteases. The envelope glycoprotein (E) undergoes a conformational rearrangement triggered by low pH that results in a class II fusion event required for viral entry. The E protein (aa 291-791) contains a three-domain structure where domain I is an eight-stranded β-barrel in the center portion of the protein (aa 1-51, 134-195, and 284-297). The DII domain consists of 170 residues inserted into DI (aa 52-133 and 196-283). At the distal end of DII domain is a fusion loop (aa 98-110) and a conserved glycine-rich, hydrophobic sequence, which is important for flaviviral fusion. The third domain, DIII, is an Ig-like domain with seven β-strand and has been implicated in receptor binding. The E protein also has a single N-linked glycosylation site at Asn 154, located within the ectodomain of prM domain and is cleaved by cellular enzymes during viral particle maturation. Clone E60 specifically binds to the DII fusion loop and displays limited neutralizing activity and even at higher doses neutralization activity is shown to be between 26 and 68%.
