Background

SARS-CoV-2 Nonstructural Protein 8 (NSP8) is one of the sixteen nonstructural proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19 (1). SARS-CoV-2 NSP8 is 198 amino acids (aa) with a theoretical molecular weight of 21.9 kDa (1,2). The amino acid sequence alignment of SARS-CoV and SARS-CoV-2's NSP8 has 97.5% sequence identity and 100% sequence similarity (1). SARS-CoV-2 NSP8 heterodimerizes with NSP7, which forms a complex with NSP12 (1-4). NSP8 alone in its monomeric form can also complex with NSP12, generating the RNA polymerase complex (1,4). Additionally, NSP8 is shown to interact with the SARS-CoV-2 open reading frame 6 (ORF6), encouraging RNA polymerase activity (1).
