Comments
The VEE nsP2 has several enzymatic activities and is a multifunctional protein that is important for a functional alphavirus replication complex. nsP2 is the only VEE protein that is present in the nucleus. V526A/L528A double mutations abolished VEE viability.

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.
