Enables protein domain specific binding activity. Predicted to be involved in several processes, including nucleocytoplasmic transport; positive regulation of protein import into nucleus; and protein localization to nucleolus. Predicted to be located in several cellular components, including centriole; midbody; and nucleus. Predicted to be part of RNA nuclear export complex. Predicted to be active in cytoplasm and nucleus. Predicted to colocalize with chromatin. Is expressed in brain ventricular layer; orbito-sphenoid; submandibular gland primordium; and vibrissa. Human ortholog(s) of this gene implicated in type 1 diabetes mellitus. Orthologous to human RAN (RAN, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
