"Homooctamer. Interacts with VP1; this interaction is weak. Interacts with NSP5; this interaction leads to up-regulation of NSP5 phosphorylation and formation of viral factories. Interacts with host DCP1A, DCP1B, DDX6, EDC4 and EIF2S1/eIF2-alpha; these interactions are probably part of the sequestration of some host SGs and PBs proteins in viral factories."xsd:string
