UniProtKB - Q7SZC2 (XPO2_DANRE)
Protein
Exportin-2
Gene
cse1l
Organism
Danio rerio (Zebrafish) (Brachydanio rerio)
Status
Functioni
Export receptor for importin alpha. Mediates importin-alpha re-export from the nucleus to the cytoplasm after import substrates have been released into the nucleoplasm (By similarity).
Negatively regulates fluid secretion and plays a role in fluid homeostasis by down-regulating cftr activity (PubMed:20933420).
