NP (RSV)

Nucleoprotein encapsidates the viral RNA genome by forming a left-handed helical nucleocapsid that protects the RNA from nucleases. RNA replication depends on the availability of soluble nucleoprotein. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. Together with the phosphoprotein, sequesters host NF-kappa-B in inclusion bodies (IBs) thereby inhibiting this host defense pathway. May also act as a modulator of the innate immune response by sequestration of host IFIH1/MDA5 and MAVS into IBs.
