Enables 6-phosphofructo-2-kinase activity and fructose-2,6-bisphosphate 2-phosphatase activity. Predicted to be involved in fructose 2,6-bisphosphate metabolic process. Predicted to be active in cytosol. Orthologous to human PFKFB4 (6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4). [provided by Alliance of Genome Resources, Apr 2022]
