Comments
Integral to plant immune response, Enhanced Disease Susceptibility 1 has differentiated roles dependent upon nucleo-cytoplasmic shuttling. The EDS1 nuclear pool is crucial for resistance to biotrophic and hemi-biotrophic pathogens as well as transcriptional reprogramming, whereas the cytoplasmic pool is necessary for resistance to and restriction of host cell death at infection sites. It is hypothesized that cytoplasmic and nuclear EDS1 pools communicate through the nuclear pores to coordinate resistance and cell death programs. Nuclear EDS1 is required for TIR-NB-LRR-induced reprogramming of defense gene expression and resistance. EDS1 needs to accumulate to a sufficient level inside nuclei to signal a full innate immune response against virulent and avirulent pathogens. With regards to the NES, although a critical residue is noted, mutation of the residue in the EDS1 NES did not lead to obvious relocalization of YFP-tagged EDS1 protein in transient plant expression assays. Rev-like and PKI-like NES were noted, but not proven to be sufficient. Amino acids 528-537 were identified as NES, but not experimentally proven to be sufficient. Ratjadone A, which blocks CRM1-dependent nuclear export by identical mechanisms as LMB, demonstrated that the EDS1 nuclear export is CRM1-dependent.

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.
