Protein Domain : RNA-directed RNA polymerase, thumb domain, Flavivirus IPR046811

Type  Domain
Description  Flaviviruses produce a large polyprotein from the ssRNA genome, encoding structural proteins required for virus assembly and non-structural (NS1-5) proteins involved in replication of the viral genome [ , , ]. This polyprotein is cleaved by viral and cellular proteases to produce mature viral proteins. NS5 is the largest mature viral protein and contains a N-terminal methyltransferase (MTase) domain separated by a short linker from the C-terminal RNA-directed RNA polymerase domain (RdRp) that adopts a characteristic right-handed fingers-palm-thumb fold and possesses a number of short regions and motifs homologous to other RdRps [, ]. This entry represents the thumb domain of NS5 RdRp. NS5 binds to a the stem loop A (SLA) at the 5' extremity of Flavivirus genome and regulates translation of the viral genome [].
