Comments
SYFA/PheRS is the enzyme responsible for the ligation of Phe to its tRNA. It is identified in proteomics study by Kirli et al. as a CRM1 binder, suggesting that it may be an export adaptor for pre-40S particles. Export activity is verified as GFP- and GFP-NLS-fusions in an LMB-sensitive manner. No putative NES have been identified yet.

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.
