Protein
Nucleoprotein
Gene
N
Organism
Bat coronavirus 279/2005 (BtCoV) (BtCoV/279/2005)
Status
Functioni
Packages the positive strand viral genome RNA into a helical ribonucleocapsid (RNP) and plays a fundamental role during virion assembly through its interactions with the viral genome and membrane protein M. Plays an important role in enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication.UniRule annotation

Post-translational modificationi
ADP-ribosylated. The ADP-ribosylation is retained in the virion during infection.UniRule annotation
Phosphorylated on serine and threonine residues.UniRule annotation
Keywords - PTMi
ADP-ribosylation, PhosphoproteinInteractioni
Subunit structurei
Homooligomer. Both monomeric and oligomeric forms interact with RNA.
Interacts with protein M.
Interacts with NSP3; this interaction serves to tether the genome to the newly translated replicase-transcriptase complex at a very early stage of infection.
