    Summary
    Enables GTPase activity. Involved in several processes, including exonucleolytic trimming to generate mature 3'-end of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA); nucleocytoplasmic transport; and regulation of nucleocytoplasmic transport. Located in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in type 1 diabetes mellitus. Orthologous to human RAN (RAN, member RAS oncogene family).
