Comments
Essential for DNA mismatch repair and involved in cell-cycle regulation, MLH1 contains both NES and NLS. MLH1 forms a heterodimer with PMS2 (MutLα), and both are known to traverse the nuclear membrane, but only MLHI was found to interact with CRM1. A mutated NES variant is found in patients with Lynch syndrome, and the nucleo-cytoplasmic shuttling of MutLα is implicated in the genesis of the syndrome.

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.
