Comments
Opioid growth factor receptor (OGFr) has a role in growth inhibition in response to opioid growth factor (OGF). Kren et al. identified a putative NES in 217-225 matching traditional NES consensus. However, mutations to leucines in full-length proteins caused cytoplasmic accumulation, inconsistent with NES activity; the mutations however rendered the protein not LMB-sensitive but non-functional. This is also the case for NLS mutations. Deletion of 6 out of the 7 tandem repeats at the C-terminal of the protein caused nuclear accumulation, but the protein is non-functional as well. Peptide alone has LMB-sensitive nuclear export activity.

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.
