Function

[POLG_BVDVC] Initial binding to target cell probably involves interaction of E(rns) with glycosaminoglycans. E1 and/or E2 are responsible of cell attachment with CD46 and subsequent fusion after internalization of the virion by endocytosis (By similarity). P7 forms a leader sequence to properly orient NS2 in the membrane (By similarity). Uncleaved NS2-3 is required for production of infectious virus. NS2 protease seems to play a vital role in viral RNA replication control and in the pathogenicity of the virus. NS3 displays three enzymatic activities: serine protease, NTPase and RNA helicase. NS4A is a cofactor for the NS3 protease activity (By similarity). RNA-directed RNA polymerase NS5 replicates the viral (+) and (-) genome.

Publication Abstract from PubMed

Viral RNA-dependent RNA polymerases (RdRp) differ from DNA-dependent RNA polymerases, DNA-dependent DNA polymerases, and reverse transcriptases in that RdRps contain "fingertips" consisting of several polypeptide strands in the fingers domain interacting with the thumb domain. The crystal structure of bovine viral diarrhea virus (BVDV) RdRp containing an Asn438 duplication shows that the "N-terminal domain," which occurs only in pestiviruses such as BVDV, interacts with the polymerase component of the same polypeptide chain. This contrasts with the domain swapping observed in the previously determined structure of the BVDV NADL strain RdRp. By comparison with the NADL structure and through the use of biochemical data, it is possible that the N-terminal domain, in conjunction with the fingertips, is required to bind and assist the translocation of the RNA template. The partial disorder of the loop containing the additional Asn438 residue may explain the low replication rate of the recombinant compared with the wild-type virus.
