XPO1（exportin 1），癌症关联基因，基因ID：7514，该细胞周期调控基因编码一种蛋白质，介导富含亮氨酸的核输出信号（NES）依赖性蛋白质转运。该蛋白特异性地抑制rev和u-snrnas的核输出。它通过控制细胞周期蛋白B、MPAK和MAPKAP激酶2的定位，参与控制一些细胞过程。这种蛋白质还调节NFAT和AP-1。[由RefSeq提供，2015年1月]This cell-cycle-regulated gene encodes a protein that mediates leucine-rich nuclear export signal (NES)-dependent protein transport. The protein specifically inhibits the nuclear export of Rev and U snRNAs. It is involved in the control of several cellular processes by controlling the localization of cyclin B， MPAK， and MAPKAP kinase 2. This protein also regulates NFAT and AP-1.
