General description
Nucleoprotein (UniProt: P59595/P0DTC9; also known as Nucleocapsid protein, NC, Protein N) is encoded by the N gene (Gene ID: 1489678) in Human SARS coronavirus. The SARS-CoV-2 (COVID-19 causing virus) is a positive-strand RNA virus that causes severe respiratory syndrome in human. The mature SARS-CoV-2 contains 4 structural proteins: Envelope (E), Membrane (M), Nucleocapsid (N), and the Spike protein (S). Nucleoprotein of SARS-CoV and SARS-CoV-2 is a homooligomeric protein that packages the positive strand viral genome RNA into helical ribonucleocapsid and plays a role in virion assembly through its interactions with the viral genome and membrane protein M. It plays an important role in enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication. The RNA binding region of SARS-CoV and SARS-CoV-2 is localized to amino acids 42-187 and 41-186, respectively. Lack of cysteine is one of the common features in nucleoprotein from different coronaviruses. The complete N protein of SARS-CoV and COV-2 is a highly basic with positive net charges and high pI (10.11). Its N-terminal region is more basic with positive charge, while the C-terminal region is acidic with negative charge. The middle region of nucleoprotein displays relatively higher hydrophobicity and the two termini display greater hydrophilicity. Nucleoprotein can undergo phosphorylation at multiple serines by GSK-3, CKII, Akt, CDKs, and Polo-like kinases. Some of these phosphorylation events are essential for RNA binding, oligomerization and localization to nucleoli. Phosphorylation is also required for recruitment of host RNA helicase DDX1 (DEAD-Box Helicase 1) that facilitates template readthrough and enables longer subgenomic mRNA synthesis. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
