CRM1: Antibodies

Official Gene Symbol: XPO1 Gen Bank Accession Number: NP_003391 Gene ID: 7514 (human) Gene Map Locus: 2p16 (human) 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.
