Comments
MKP3 is one of the 10 distinct MKPs in mammalian cells. It preferentially dephosphorylates the stress-activated MAP kinases c-Jun amino-terminal kinase and p38. The NES is also conserved in MKP-4, whose export is LMB sensitive too.

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.
