Comments
pUL37 is a tegument protein essential for cytoplasmic envelopment during viral egress. Funk et al. found this protein to have nuclear export activity using Nuclear EXport Trapped by RAPamycin (NEX-TRAP), protein tested in this study contains a 11-residue deletion in the N-terminus. However, the NES is shown to be part of an alpha-helical domain in the available PDB structure and doesn't appear to be accessible unless the protein unfolds.

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.
