DcpS scavenger-decapping enzyme belongs to a newly identified class of cap-binding proteins that exhibit intrinsic hydrolytic activity. DcpS performs the final step of mRNAs degradation by hydrolyzing the residual cap. Besides the cytoplasmic function, Shen et al. found that DcpS is a shuttling protein with the help of a classic NLS and a NES, and facilitate first intron splicing in the nucleus.
Doubts about NESs: The proposed NES failed to bind CRM1 in GST-pulldown assay (Chook Lab, unpublished results).

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.
