1 Spindle assembly is spatially regulated by a chromosome-derived Ran- GTP gradient. Guanosine Triphosphate RAN, member RAS oncogene family Homo sapiens
2 However, it is unclear whether the Ran-GTP gradient equivalently activates SAFs that localize at distinct spindle regions. Guanosine Triphosphate RAN, member RAS oncogene family Homo sapiens
3 We demonstrated that Ran-GTP and importin-beta coordinately promote HURP"s dynamic microtubule binding-dissociation cycle, which maintains HURP near chromosomes during metaphase. Guanosine Triphosphate RAN, member RAS oncogene family Homo sapiens
