Protein

Glucose-6-phosphate isomerase

Gene

Gpi

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Besides it's role as a glycolytic enzyme, mammalian GPI can function as a tumor-secreted cytokine and an angiogenic factor (AMF) that stimulates endothelial cell motility. GPI is also a neurotrophic factor (Neuroleukin) for spinal and sensory neurons.

Catalytic activityi

D-glucose 6-phosphate = D-fructose 6-phosphate.

Pathwayi: glycolysis

This protein is involved in step 2 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Glucose-6-phosphate isomerase (Gpi), Glucose-6-phosphate isomerase (Gpi1), Glucose-6-phosphate isomerase (Gpi1), Glucose-6-phosphate isomerase (Gpi1)
  3. ATP-dependent 6-phosphofructokinase, liver type (Pfkl), ATP-dependent 6-phosphofructokinase (Pfkp), ATP-dependent 6-phosphofructokinase (Pfkm), ATP-dependent 6-phosphofructokinase, platelet type (Pfkp), ATP-dependent 6-phosphofructokinase, muscle type (Pfkm)
  4. Fructose-bisphosphate aldolase (Aldoart1), Fructose-bisphosphate aldolase (Aldoa), Fructose-bisphosphate aldolase (Aldoa), Fructose-bisphosphate aldolase (Aldoart2), Fructose-bisphosphate aldolase (Aldoart1), Fructose-bisphosphate aldolase (Aldoa), Fructose-bisphosphate aldolase (Aldoa), Fructose-bisphosphate aldolase (Aldob), Fructose-bisphosphate aldolase C (Aldoc), Fructose-bisphosphate aldolase A (Aldoa), Fructose-bisphosphate aldolase B (Aldob), Fructose-bisphosphate aldolase (Aldob)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose, the pathway glycolysis and in Carbohydrate degradation.
