Predicted to enable GTP binding activity; GTPase activity; and protein homodimerization activity. Predicted to be involved in several processes, including positive regulation of NLRP3 inflammasome complex assembly; positive regulation of cytokine production; and protein homotetramerization. Predicted to act upstream of or within response to bacterium. Predicted to be located in Golgi apparatus and perinuclear region of cytoplasm. Predicted to be active in cytoplasmic vesicle. Orthologous to human GBP5 (guanylate binding protein 5). [provided by Alliance of Genome Resources, Apr 2022]
