Nipah virus, a member of the Paramyxoviridae family, is a highly pathogenic nonsegmented, negative-sense RNA virus (nsNSV) which causes severe neurological and respiratory illnesses in humans. There are no available drugs or vaccines to combat this virus. A complex of large polymerase protein (L) and phosphoprotein (P) of Nipah virus supports replication and transcription and affords a target for antiviral drug development. Structural information required for drug development is lacking. Here we report the 2. 9-angstrom cryo-electron microscopy structure of the Nipah virus polymerase-phosphoprotein complex. The structure identifies conserved amino acids likely important for recognition of template RNA by nsNSVs and reveals the locations of mutation-prone sites among Nipah virus strains, which may facilitate the development of therapeutic agents against Nipah virus by targeting regions unaffected by these mutation sites.
