West Nile virus core protein: Tetramer structure and ribbon formation

Academic Article


  • We have determined the crystal structure of the core (C) protein from the Kunjin subtype of West Nile virus (WNV), closely related to the NY99 strain of WNV, currently a major health threat in the U.S. WNV is a member of the Flaviviridae family of enveloped RNA viruses that contains many important human pathogens. The C protein is associated with the RNA genome and forms the internal core which is surrounded by the envelope in the virion. The C protein structure contains four α helices and forms dimers that are organized into tetramers. The tetramers form extended filamentous ribbons resembling the stacked α helices seen in HEAT protein structures.
