Comments
SRP54 is the protein responsible for recognition of the signal sequence of presecretory protein and directs them to TRAM for translocation across the ER membrane. SRP54 is identified in proteomics study by Kirli et al. as a CRM1 binder. 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.
