Protein detail:
| Protein name | Nucleocapsid Phosphoprotein |
| Uniprot protein ID | P0DTC9 |
| Protein length | 419 amino acids |
| Protein description | The Nucleocapsid Phosphoprotein has a modular organization which can be divided into intrinsically disordered regions (IDRs) and conserved structural regions according to the sequence characteristics. The IDRs include three modules: N-arm, central Ser/Arg-rich flexible linker region (LKR), and C-tail, while the conserved structural regions including two modules: N-terminal domain (NTD) and C-terminal domain (CTD). In the primary structure, NTD and CTD are connected by LKR and are usually flanked by N-arm and C-tail. The nucleocapsid phosphoprotein is a structural protein that binds to, protects the viral RNA genome and is involved in packaging the RNA into virus particles. The N protein has been suggested as an antiviral drug target. |

| Evidence | The amino acid substitutions S (D614G) in the spike protein and NSP12b in the non-structural protein (NSP) occurred in all SARS-CoV-2 isolates. In addition, 10 of the 11 SARS-CoV-2 isolates carried the NSP2 (Y537Y), NSP3 (F106F), and ORF3a (Q57H) substitutions (Table 1). |
