SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,nucleus

basic FUNCTION	catalyzing the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate and inorganic phosphate
	important roles of FBP1 expression in lung cancer development and progression

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

carbohydrate

signaling

	gluconeogenesis
	FBP1 signaling pathway may serve an important role in normal follicle growth and hyperandrogenism&
	8209;induced abnormal development, which may be associated with abnormal glucose metabolism induced by high concentrations of testosterone

a component

INTERACTION

DNA

RNA

small molecule	metal binding,
	Zn2+

protein	FBP1 guides the cellular localization of ALDOB
	FBP1 down-regulation enhanced the activity of WNT/CTNNB1 pathway and increased the level of its downstream targets, including MYC and MMP7
	CBX3 negatively regulated FBP1 expression
	CBX3 serves as a positive regulator of aerobic glycolysis via suppressing of the FBP1 in pancreatic cancer cells
	HSF2 could regulate aerobic glycolysis by suppression of FBP1 to support uncontrolled proliferation of hepatocellular carcinoma cells
	TRIM47 promoted the aerobic glycolysis of pancreatic cancer cells, which was largely dependent on the direct binding to and ubiquitination of FBP1
