It forms a hexadecameric supercomplex with NSP8 that adopts a hollow cylinder-like structure [2]. The dimensions of the central channel and positive electrostatic properties of the cylinder imply that it confers processivity on RNA-dependent RNA polymerase [2]. NSP7 and NSP8 heterodimers play a role in the stabilisation of NSP12 regions involved in RNA binding and are essential for a highly active NSP12 polymerase complex [3].

The dimensions of the central channel and positive electrostatic properties of the cylinder imply that it confers processivity on RNA-dependent RNA polymerase [1]. NSP7 and NSP8 heterodimers play a role in the stabilisation of NSP12 regions involved in RNA binding and are essential for a highly active NSP12 polymerase complex [2]. It has been demonstrated that NSP8 acts as an oligo(U)-templated polyadenylyltransferase but also has robust (mono/oligo) adenylate transferase activities [3]. NSP8 has N- and C-terminal D/ExD/E conserved motifs, being the N-terminal motif critical for RNA polymerase activity as these residues are part of the Mg2-binding active site [4].
