Crystal structure of the rabies virus nucleoprotein-RNA complex
Overview
Negative-strand RNA viruses condense their genome into a helical, nucleoprotein-RNA complex, the nucleocapsid, which is packed into virions, and serves as a template for the RNA-dependent RNA polymerase complex. The, crystal structure of a recombinant rabies virus nucleoprotein-RNA complex, organized in an undecameric ring, has been determined at 3.5 angstrom, resolution. Polymerization of the nucleoprotein is achieved by domain, exchange between protomers, with flexible hinges allowing nucleocapsid, formation. The two core domains of the nucleoprotein clamp around the RNA, at their interface and shield it from the environment. RNA sequestering by, nucleoproteins is likely a common mechanism used by negative-strand RNA, viruses to protect their genomes from the innate immune response directed, against viral RNA in human host cells at certain stages of an infectious, cycle.
