The association of Zika virus (ZIKV) infections with microcephaly has resulted in an ongoing public-health emergency. Here we report the crystal structure of a C-terminal fragment of ZIKV nonstructural protein 1 (NS1), a major host-interaction molecule that functions in flaviviral replication, pathogenesis and immune evasion. Comparison with West Nile and dengue virus NS1 structures reveals conserved features but diverse electrostatic characteristics at host-interaction interfaces, thus possibly implying different modes of flavivirus pathogenesis.

The crystal structure of the C-terminal region of Zika virus nonstructural protein 1 (NS1) reveals a fold similar to those of other flaviviruses (dengue and West Nile viruses) but different surface electrostatic features.
