Comments
NS5 is the most highly conserved of all Dendue virus proteins. It shuttles between the nucleus and the cytoplasm of infected cells but is mostly nuclear. It is important for viral replication in the cytoplasm and in the nucleus it inhibits induction of IL8 to reduce antiviral response. NS5 has an N-terminal S-adenosyl methyltransferase domain, followed by an interdomain linker region that contains both an NLS and the NES and a C-terminal RNA polymerase domain. In the linker, the NES overlaps with a segment that is both an NLS that binds Imp-beta (residues 320-368) and binds NS3. NS5 export critical for infection and NES mutation reduces IL-8 induction. Note that there is inconsistency between the sequence in the paper and the one in SwissProt. AA 334 and 335 are valines in SwissProt, whereas in the paper, they are isoleucines.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
