In addition to structural roles of Keratin-17, Escobar-Hoyos et al. found that it mediates cancer cell cycle progression through mediating the nuclear export of p27KIP1. Putative NES is identified in 194-199 (186-199 matches traditional NES consensus). NES mutant of K17 retained in the nucleus and appeared to have a higher molecular weight, possibly due to accumulation of post-translational modifications. This study also concluded that p27KIP1 piggy-backs on K17 for CRM1-dependent export as LMB and K17 NES mutation both caused p27KIP1 nuclear accumulation.

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.
