CC -!- FUNCTION: Packages the positive strand viral genome RNA into a helical
CC ribonucleocapsid (RNP) and plays a fundamental role during virion
CC assembly through its interactions with the viral genome and membrane
CC protein M. Plays an important role in enhancing the efficiency of
CC subgenomic viral RNA transcription as well as viral replication.
CC {ECO:0000255|HAMAP-Rule:MF_04097}.
CC -!- SUBUNIT: Homooligomer. Both monomeric and oligomeric forms interact
CC with RNA. Interacts with protein M. Interacts with NSP3; this
CC interaction serves to tether the genome to the newly translated
CC replicase-transcriptase complex at a very early stage of infection.
CC {ECO:0000255|HAMAP-Rule:MF_04097}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04097}. Host
CC endoplasmic reticulum-Golgi intermediate compartment
CC {ECO:0000255|HAMAP-Rule:MF_04097}. Host Golgi apparatus
CC {ECO:0000255|HAMAP-Rule:MF_04097}. Note=Located inside the virion,
CC complexed with the viral RNA. Probably associates with ER-derived
CC membranes where it participates in viral RNA synthesis and virus
CC budding. {ECO:0000255|HAMAP-Rule:MF_04097}.
CC -!- PTM: ADP-ribosylated. The ADP-ribosylation is retained in the virion
CC during infection. {ECO:0000255|HAMAP-Rule:MF_04097}.
CC -!- PTM: Phosphorylated on serine and threonine residues.
CC {ECO:0000255|HAMAP-Rule:MF_04097}.
CC -!- SIMILARITY: Belongs to the gammacoronavirus nucleocapsid protein
CC family. {ECO:0000255|HAMAP-Rule:MF_04097}.
