Enables fructose-2,6-bisphosphate 2-phosphatase activity and kinase binding activity. Involved in several processes, including monocarboxylic acid metabolic process; positive regulation of glucokinase activity; and positive regulation of insulin secretion. Located in cytoplasm. Orthologous to human PFKFB2 (6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 2). [provided by Alliance of Genome Resources, Apr 2022]
