[ | [https://www.uniprot.org/uniprot/POLG_NVN68 POLG_NVN68] Protein p48 may play a role in viral replication by interacting with host VAPA, a vesicle-associated membrane protein that plays a role in SNARE-mediated vesicle fusion. This interaction may target replication complex to intracellular membranes.<ref>PMID:569187</ref> <ref>PMID:11160659</ref> NTPase presumably plays a role in replication. Despite having similarities with helicases, does not seem to display any helicase activity.<ref>PMID:569187</ref> <ref>PMID:11160659</ref> Protein P22 may play a role in targeting replication complex to intracellular membranes.<ref>PMID:569187</ref> <ref>PMID:11160659</ref> Viral genome-linked protein is covalently linked to the 5'-end of the positive-strand, negative-strand genomic RNAs and subgenomic RNA. Acts as a genome-linked replication primer. May recruit ribosome to viral RNA thereby promoting viral proteins translation.<ref>PMID:569187</ref> <ref>PMID:11160659</ref> 3C-like protease processes the polyprotein: 3CLpro-RdRp is first released by autocleavage, then all other proteins are cleaved. May cleave host polyadenylate-binding protein thereby inhibiting cellular translation (By similarity).<ref>PMID:569187</ref> <ref>PMID:11160659</ref> RNA-directed RNA polymerase replicates genomic and antigenomic RNA by recognizing replications specific signals. Transcribes also a subgenomic mRNA by initiating RNA synthesis internally on antigenomic RNA. This sgRNA encodes for structural proteins. Catalyzes the covalent attachment VPg with viral RNAs (By similarity).<ref>PMID:569187</ref> <ref>PMID:11160659</ref> | ||
