Predicted to enable small GTPase binding activity. Predicted to be involved in protein import into nucleus. Predicted to act upstream of or within RNA export from nucleus and protein export from nucleus. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of nuclear pore central transport channel. Orthologous to human NXT1 (nuclear transport factor 2 like export factor 1). [provided by Alliance of Genome Resources, Apr 2022]
