| Function | Catalyzes the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate in the presence of divalent cations, acting as a rate-limiting enzyme in gluconeogenesis. Plays a role in regulating glucose sensing and insulin secretion of pancreatic beta-cells. Appears to modulate glycerol gluconeogenesis in liver. Important regulator of appetite and adiposity; increased expression of the protein in liver after nutrient excess increases circulating satiety hormones and reduces appetite-stimulating neuropeptides and thus seems to provide a feedback mechanism to limit weight gain. {ECO:0000269|PubMed:16497803, ECO:0000269|PubMed:18375435, ECO:0000269|PubMed:22517657}. |
| Tissue Specificity | Expressed in pancreatic islets. {ECO:0000269|PubMed:18375435}. |
