Comments
Gln3p is a GATA-type yeast transcription activator that regulates response to nitrogen. Gln3p is hyperphosphorylated and resides in the cytoplasm when there is adequate nitrogen, upon nitrogen depletion or rapamycin treatment, it is dephosphorylated and translocated to the nucleus for its action. Carvalho et al. found that Gln3p is mislocalized to the nucleus in temp-sensitive CRM1 strain under restrictive temp with or without rampamycin in high quality nitrogen. Putative NES can be identified in residues 336-345 which matches traditional NES consensus. Binding to CRM1 is shown by yeast-2-hydrid assay. Deletion of NES causes nuclear accumulation.

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.
