Predicted to enable GTP binding activity; GTPase activity; and protein homodimerization activity. Predicted to be involved in cellular response to interferon-gamma; defense response to Gram-positive bacterium; and defense response to protozoan. Predicted to act upstream of or within adhesion of symbiont to host and cellular response to interferon-beta. Predicted to be located in several cellular components, including Golgi apparatus; cytosol; and perinuclear region of cytoplasm. Predicted to be active in cytoplasmic vesicle. Orthologous to several human genes including GBP7 (guanylate binding protein 7). [provided by Alliance of Genome Resources, Apr 2022]
