Comments
Nmd3 export 60S ribosomal subunit from nucleus. Trotta et al. demonstrated that human NMD3 shuttles in a LMB sensitive manner and identified the functional signal and key mutations that affect in vivo export of NMD3. In addition, Thomas et al. showed NMD3 binds to CRM1 in vitro in the presence of RanGTP. Ho et al. did the early work on yeast NMD3p (Uniprot:P38861). In addition to the NES in human (aa 490-505), they proposed another possible NES (weaker, aa 419-468) based on the fact that deletion including this conserved domain resulted in a stronger dominant-negative phenotype. Similar findings were reported by Gadal et al. This weaker NES is not well conserved in human (possibly 426-461).

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.
