Comments
STAT3 is one of the seven members of the STATs family. It plays complex roles in proliferation, survival, and development. STAT3 posses important function within the N-terminus and shuttles between the nucleus and the cytoplasm in unstimulated cells in a LMB-sensitive manner. It was proposed that out of the three NESs, NES(404-414) and NES(524-535) regulate the basal export, whereas NES(306-318) plays an important role in postreceptor-simulated export. Stat3 shares >50% sequence identity with Stat1. All three NESs from Stat3 are conserved in Stat1. Note that NES(524-535) in Stat3 has not been verified in STAT1. But it is accessible. In addition, aa 197-205 in Stat1 was proposed to be a NES. The last hydrophobic residues don't align well. Plus, McBride et al. showed that aa 1-369 of Stat1 don't bind CRM1.

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.
