Comments
HIV-1 Vpr is packaged into new virions and is suspected to be important for transport of the viral preintegration complex (PIC) through the nuclear pore complex. The minimal NES has not been mapped but mutations suggest that it is in the 2nd helix of Vpr (residues 60-71).

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.
