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. |

| Title | Multiple detection and spread of novel strains of the SARS-CoV-2 B.1.177 (B.1.177.75) lineage that test negative by a commercially available nucleocapsid gene real-time RT-PCR |
| Author | Laura Amato, Lucija Jurisic, Ilaria Puglia, Valeria Di Lollo, Valentina Curini |
| Evidence | Thus, B.1.177.75 virus variants containing the 28932C>T mutation were diagnosed as positive for SARS-CoV-2 RNA with the canonical diagnostic +/+/+ pattern, while B.1.177.75 virus variants containing both the 28932C>T and 28948C>T mutation resulted in +/+/- for ORF1ab, S and N genes, respectively. |
