CC   -!- FUNCTION: Guanine-nucleotide releasing factor that promotes the
CC       exchange of Ran-bound GDP by GTP, and thereby plays an important role
CC       in RAN-mediated functions in nuclear import and mitosis. Contributes to
CC       the generation of high levels of chromosome-associated, GTP-bound RAN,
CC       which is important for mitotic spindle assembly and normal progress
CC       through mitosis. Via its role in maintaining high levels of GTP-bound
CC       RAN in the nucleus, contributes to the release of cargo proteins from
CC       importins after nuclear import (By similarity). Involved in the
CC       regulation of onset of chromosome condensation in the S phase
CC       (PubMed:2361953). Binds both to the nucleosomes and double-stranded DNA
CC       (By similarity). {ECO:0000250|UniProtKB:P18754,
