This gene encodes a member of the family of bifunctional 6-phosphofructo-2-kinase:fructose-2,6-biphosphatase enzymes. The enzyme forms a homodimer that catalyzes both the synthesis and degradation of fructose-2,6-biphosphate using independent catalytic domains. Fructose-2,6-biphosphate is an activator of the glycolysis pathway and an inhibitor of the gluconeogenesis pathway. Consequently, regulating fructose-2,6-biphosphate levels through the activity of this enzyme is thought to regulate glucose homeostasis. Multiple alternatively spliced transcript variants have been found for this gene.PFKFB1 (6-Phosphofructo-2-Kinase/Fructose-2,6-Biphosphatase 1) is a Protein Coding gene. Among its related pathways are Glucose metabolism and Glucagon signaling pathway. GO annotations related to this gene include identical protein binding and kinase binding. An important paralog of this gene is PFKFB4.
