Comments
Ran1p is yeast RanGAP1, the GTPase-activating protein for Ran which helps maintain the RanGTP/GDP gradient required for nucleocytoplasmic transport. Mouse homolog is listed in entry #338. In yeast, Ran1p is predominantly cytosolic. Two putative NES can be found in 316-357 and this region can direct reporter protein to the cytosol. The first NES motif 316-333 has less activity than the whole 316-357 fragment and mutation of L326 and L328 is sufficient to abolish export activity. The second NES motif 329-357 appears to have stronger NES activity than the former motif. CRM1 dependence was demonstrated by temperature sensitive CRM1 strain.

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.
