[[http://www.uniprot.org/uniprot/POLG_FCVF9 POLG_FCVF9]] NTPase presumably plays a role in replication. Despite having similarities with helicases, does not seem to display any helicase activity (By similarity). 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 (By similarity). Protease-polymerase p76 processes the polyprotein: Pro-Pol is first released by autocleavage, then all other proteins are cleaved. Cleaves host translation initiation factor eIF4G1 and eIF4G2 thereby inducing a shutdown of host protein synthesis. This shutdown may not prevent viral mRNA from being translated since viral Vpg replaces the cap. May cleave host polyadenylate-binding protein thereby inhibiting cellular translation. It is also a RNA-directed RNA polymerase which replicates genomic and antigenomic viral RNA by recognizing 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).
