Catalyzes the reversible conversion of beta-D-fructose 1,6-bisphosphate (FBP) into two triose phosphate and plays a key role in glycolysis and gluconeogenesis (By similarity). In addition, may also function as scaffolding protein (By similarity). beta-D-fructose 1,6-bisphosphate = D-glyceraldehyde 3-phosphate + dihydroxyacetone phosphate Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 4/4. Homotetramer. Interacts with SNX9 and WAS. Interacts with FBP2; the interaction blocks FBP2 inhibition by physiological concentrations of AMP and reduces inhibition by Ca(2+) (By similarity). In skeletal muscle, accumulates around the M line and within the I band, colocalizing with FBP2 on both sides of the Z line in the absence of Ca(2+). Expressed in muscle, brain and hepatoma cells. In vertebrates, three forms of this ubiquitous glycolytic enzyme are found, aldolase A in muscle, aldolase B in liver and aldolase C in brain. Belongs to the class I fructose-bisphosphate aldolase family.
