Abstract: | Ran(Ras-related nuclear protein)is an extremely abundant GTPase with small molecular weight in eucaryotic cell,it plays very important roles in the nucleo-cytoplasmic transportantion.The functions of Ran and its main binding proteins are briefly introduced in this article; and the roles in the nucleo-cytoplasmic transportation, mitosis and post-mitotic nuclear assembly are emphatically introduced. Furthermore,the relationship between Ran's functions are also discussed in this review. |
