Open and closed forms of assembled henipavirus nucleoprotein suggest structural basis of genome access

Abstract Henipaviruses, such as Nipah virus, can cause deadly illness and constitute WHO blueprint priorities due to their pandemic potential. Their genomes are packaged within a nucleocapsid consisting of viral nucleoproteins (N). Now, it is unclear how the encapsidated genome is released from N to allow the viral polymerase to read its sequence. Here, we present the high-resolution cryo-EM structure of a helical N-RNA filament from Langya heni…
