The ran decathlon: multiple roles of Ran.
The Ran GTPase system affects many cellular processes, including the regulation of cell cycle progression, nuclear envelope structure and function, and nucleocytoplasmic transport. The biochemical basis for the involvement of Ran in nuclear import and export has been well documented, but the direct targets of Ran in other cellular processes have not yet been identified. There is, however, mount...
متن کاملSmall GTPase Ran and Ran-binding proteins.
Abstract Like many other small GTPases, Ran functions in eukaryotic cells as a molecular switch that cycles between GTP- and GDP-bound forms. Through the proper modulation of the GTP/GDP cycle, Ran functions with a number of Ran-binding proteins to control a broad array of fundamental cellular functions, including nucleocytoplasmic transport, mitotic spindle assembly, and nuclear envelope and n...
متن کاملRan
How is Ran involved in nuclear transport? Cargo is transported through pores in the nuclear envelope, in association with carriers that bind to pore proteins called nucleoporins. A Ran–GTP gradient across the envelope is created by the asymmetric distribution of the GTPase activating protein known as RanGAP, which is in the cytosol, and of the guanine nucleotide exchange factor RanGEF in the nu...
