Predicted to enable several functions, including Hsp90 protein binding activity; cytoskeletal protein binding activity; and guanyl ribonucleotide binding activity. Predicted to be involved in several processes, including cellular response to cytokine stimulus; negative regulation of interleukin-2 production; and regulation of signal transduction. Predicted to act upstream of or within adhesion of symbiont to host; cellular response to interferon-beta; and defense response to other organism. Predicted to be located in several cellular components, including Golgi apparatus; actin cytoskeleton; and vesicle membrane. Orthologous to human GBP1 (guanylate binding protein 1).
