Background

SARS-CoV-2 Nonstructural Protein 14 (NSP14) 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 NSP14 is 527 amino acids (aa) with a theoretical molecular weight of 59.8 kDa (1-3). The amino acid sequence alignment of SARS-CoV and SARS-CoV-2's NSP14 has 95.1% sequence identity and 99.1% sequence similarity (1). Functionally, NSP14 has both 3'-5' exoribonuclease activity and N7-methyltransferase activity (1-4). The N-terminal domain of NSP14 has exoribonuclease activity (ExoN) with three conserved motifs (DE, E, and D) and belongs to the DEDD superfamily (3,4). NSP14 ExoN activity has a role in RNA proofreading during viral replication (3,4). NSP10 has been shown to interact with the exoribonuclease domain of NSP14, increasing its activity (3,4). On the other hand, the carboxyl-terminal of NSP14 has the N7-methyltransferase activity and functions in viral mRNA capping (3,4).
