Predicted to enable GTPase activator activity; RNA binding activity; and enzyme binding activity. Predicted to be involved in activation of GTPase activity; cellular response to peptide hormone stimulus; and negative regulation of protein export from nucleus. Located in perinuclear region of cytoplasm. Is expressed in several structures, including brain; genitourinary system; liver; lung; and primitive streak. Orthologous to human RANGAP1 (Ran GTPase activating protein 1). [provided by Alliance of Genome Resources, Apr 2022]
