Comments
Transport of C/D snoRNPs to nucleoli involves CRM1. Pradet-Balade et al. proposed that CRM1 controls the composition of snoRNP by the removal of Tgs1 from it. Tgs1 is the enzyme required for the m7G-cap hypermethylation of snRNA and snoRNA. Tgs1 exists as two isoforms in HeLa cells. Pradet-Balade et al. showed that the long form of Tgs1 contains a CRM1 dependent export signal and shuttles. They also showed that Tgs1 long form interacts directly with CRM1 in vivo using recombinant proteins.

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.
