Functioni

Involved in genome replication. Plays a crucial role, together with NSP2, in the formation of virus factories (viroplasms) which are large inclusions in the cytoplasm where core-like replication intermediates are assembled and RNA replication takes place. May regulate NSP2-RNA interactions during genome replication, since NSP5 competes with RNA for the same binding site on the NSP2 octamer. Binds to either ssRNA or dsRNA with similar affinities. Displays ATPase and autokinase activities (By similarity).By similarity

Post-translational modificationi

O-glycosylated.By similarity
Hyperphosphorylated on serine residues, when in dimeric form. Ser-67 phosphorylation by CK1 is required for the hyperphosphorylation of NSP5 dimer. Impaired phosphorylation is associated with a profound morphological change in virus factories and a moderate decrease in virus replication (By similarity).By similarity

Interactioni

Subunit structurei

Homodimer. Interacts with VP1. Interacts with VP2. Interacts with NSP2; this interaction leads to up-regulation of NSP5 hyperphosphorylation and formation of virus factories. Interacts with NSP6 (By similarity).By similarity
