Comments
BPV-E1 is one of the eight different proteins produced by papillomaviruses during infection. It consists of a N-terminal domain with poorly defined activity, a spacer domain, and a C-terminal DNA helicases domain. Three NESs were identified for BPV-E1. The strong one is NES, and the other two are not CRM1-dependent. AA 163-172 resembles NES consensus, but is not active.

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.
