Comments
CAV capsid protein VP1 resides in both the nucleus and the cytoplasm. VP1 localization is sensitive to LMB. Three potential NESs were predicted using NetNES and ELM programs. Deletion mutagenesis of VP1 determined that only one peptide at 375-388 supports nuclear export activities. VP2 binds VP1, and seems to exit the nucleus by piggy-backing on VP1. Uniprot code and the sequence attached in this entry is for isolate USA L-028 as the Taiwan CIA-89 isolate mentioned in the paper could not be found. The sequences are highly homologous (96% identity).

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.
