Protein

Glucose-6-phosphate isomerase

Gene

GPI

Organism
Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey)
Status
Reviewed-Annotation score: -Experimental evidence at transcript 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 (By similarity).By similarity

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
