Comments
Jensen et al. used yest-two hybrid screen in an attempt to expand the number of known NES in yeast. They identified three proteins whose localization are altered in response to LMB treatment. One of them corresponds to the later named DNA damage checkpoint protein LCD1. In untreated cell, LCD1 is distributed throughout the cell, LMB addition causes LCD1 to be entirely nucleus. In addition, they found that mutation L670A or L673A within the putative NES region (aa 660-747) causes strong nuclear accumulation. As for the other two proteins CTL1 and Ace2p, CTL1 failed to show any response to leucine mutations. They were able to show that nuclear export activity is confined to aa 42-150. However, the mutation evidence is quite vague.

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.
