Comments
TG2 catalyzes the cross-linking of proteins and regulates cell growth and death. It is found predominantly in the cytoplasm. Putative NES was identified in 657-664 within the C-terminal beta-barrel domain, which matches non-canonical NES consensus (class 3 or possibly reverse classes). Interaction with CRM1 was shown with GST-fusion XPO1, and the interaction can be abolished by LMB, however it is unclear if RanGTP was used. This work took care to not truncate the beta barrel domain into fragments and only did mutations from L to Q. The putative NES is in a folded domain but the hydrophobic residues can be seen pointing out and possibly accessible in certain conformations of the protein.

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.
