Nuclear transport receptors of karyopherin:importin-beta superfamily mediate various transport pathways between nucleus and cytoplasm. Exportin-1, a human homolog of yeast CRM1, is a novel karyopherin export receptor that mediates leucine-rich NES-dependent protein export. It interacts with RanGTP through its Ran-binding domain and also with nucleoporins including Nup214, Nup50, Nup42 and Nup159 during the process of exporting NES-containing proteins. It mediates the export of many cellular and viral proteins and ribonucleoproteins including HIV Rev Protein, ERK3, PKI, IRF-5, Cyclin-B, MAPKK, MAPKAP kinase 2, Snurportin, Cap-binding protein, and certain U snRNAs. Reports suggest exportin-1 also has a role in the regulation of NFAT and AP-1. Applications: Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1-3ug/ml Immunohistochemistry (paraffin): 10ug/ml Optimal dilutions to be determined by the researcher. Positive Control: Jurkat cell lysate Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C.
