Comments
SHIP2 specifically hydrolyzes the 5-phosphate of phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2 and is a negative regulator of PI3K (phosphoinositide 3-kinase) pathways. Three putative NESs (two classical NESs and one reverse NES) are identified by in silico prediction methods in Sendino et al. using possible XPO1/CRM1-cancer exportome proteins identified previously as putative CRM1-binders by Kirli et al. (not all proteins were validated in full-length). All NES peptides were tested using Rev(1.4)-GFP assay and showed weak activity. Putative NES in 625-643 was not tested in SRVB/A reporter with co-expression with CRM1, therefore CRM1-dependency was not demonstrated. The other two NESs showed response to CRM1 overexpression.

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.
