Comments
HDM2 is over-expressed in a variety of human tumors and acts as an inhibitor of p53. HDM2 continuously shuttles between the nucleus and the cytoplasm. The export was mediated by an NES (aa 191-205), which functions independently to export GST fusion protein.

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.
