NCIt definition : Glucose-6-phosphate isomerase (558 aa, 63 kDa) is encoded by the human GPI gene.
This protein is involved in glycolysis in as a cytoplasmic homodimer and has a secreted
monomeric form that either exhibits cytokine activity or can function as a neurotrophic
factor.;
NCIt note : The enzymatically active form of glucose-6-phosphate isomerase (GPI) is a cytosolic
homodimer. GPI expresses cytokine activity when secreted as a monomer. (UniProt);
