Background: NSP7

Non-structural protein 7 (NSP7) is one of several functional proteins released by ORF1a-encoded protease cleavage of the pp1a and pp1ab replicase polyproteins expressed from the coronavirus (CoV) genome (1). The NSPs are involved in the replication and transcription of the viral RNA and not incorporated within the virion particles. Coronaviruses include various highly pathogenic strains such as SARS-CoV, MERS-CoV and SARS-CoV-2 that have had significant impact on humans in addition to strains that have negatively impacted livestock. NSP7 is a small 83 amino acid protein that is highly conserved across coronaviruses (1). The NSP7 monomers are composed of a central core N-terminal tri-helical bundle with an additional short C-terminal helix (2). The monomeric units associate to form a large hexadecameric structure with NSP8 (2) where layers of NSP7 fill the spaces in between NSP8 units. The supercomplexes are stacked to form a channel with electrostatic properties that could allow RNA to pass through the channel to facilitate efficient replication and transcription. The NSP7/NSP8 supercomplex was thereby proposed to function as a primase for the viral RNA-dependent RNA polymerase (RdRp), NSP12 (3). In SARS-CoV-2, the RdRp has been shown to have little activity without NSP8/7 as cofactors (4) making NSP7/NSP8 critical for viral polymerase activity. NSP7 has also been shown to interact with several other viral NSP proteins, including NSP5, NSP9, and NSP13 (5) as well as multiple host cell proteins involved in membrane trafficking, signaling, and electron transport including potential drug targets such as COMT and PTGES (6).
