Predicted to enable GTP binding activity; GTPase activity; and protein homodimerization activity. Predicted to be involved in cellular response to cytokine stimulus; defense response to other organism; and protein localization to nucleus. Predicted to act upstream of or within adhesion of symbiont to host; cellular response to interferon-beta; and cellular response to lipopolysaccharide. Predicted to be located in several cellular components, including Golgi apparatus; nucleoplasm; and perinuclear region of cytoplasm. Predicted to be active in cytoplasmic vesicle. Orthologous to human GBP2 (guanylate binding protein 2). [provided by Alliance of Genome Resources, Apr 2022]
