HCoV-NL63 Nucleoprotein (NP, N) is a homodimer with nonspecific binding activity toward nucleic acids. NP packages the positive strand viral genome RNA into a helical ribonucleocapsid (RNP) and plays a fundamental role during virion assembly, enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication through its interactions with the viral genome and membrane protein M. Nucleoprotein/NP Protein, HCoV-NL63 (His) is the recombinant Virus-derived Nucleoprotein/NP protein, expressed by E. coli , with N-His labeled tag.
