Predicted to enable several functions, including Hsp90 protein binding activity; cytoskeletal protein binding activity; and guanyl ribonucleotide binding activity. Acts upstream of or within several processes, including cellular response to interferon-beta; cellular response to lipopolysaccharide; and defense response to other organism. Located in cytoplasmic vesicle and symbiont-containing vacuole membrane. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and sensory organ. Orthologous to several human genes including GBP2 (guanylate binding protein 2). [provided by Alliance of Genome Resources, Apr 2022]
