ID:G6PI_HUMAN DESCRIPTION: RecName: Full=Glucose-6-phosphate isomerase; Short=GPI; EC=5.3.1.9; AltName: Full=Autocrine motility factor; Short=AMF; AltName: Full=Neuroleukin; Short=NLK; AltName: Full=Phosphoglucose isomerase; Short=PGI; AltName: Full=Phosphohexose isomerase; Short=PHI; AltName: Full=Sperm antigen 36; Short=SA-36; FUNCTION: 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 ACTIVITY: D-glucose 6-phosphate = D-fructose 6- phosphate. PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3- phosphate and glycerone phosphate from D-glucose: step 2/4. SUBUNIT: Homodimer in the catalytically active form, monomer in the secreted form. SUBCELLULAR LOCATION: Cytoplasm. Secreted. PTM: Phosphorylation at Ser-185 by CK2 has been shown to decrease enzymatic activity and may contribute to secretion by a non- classical secretory pathway. PTM: ISGylated. DISEASE: Defects in GPI are the cause of hemolytic anemia non- spherocytic due to glucose phosphate isomerase deficiency (HA- GPID) [MIM:613470]. It is a form of anemia in which there is no abnormal hemoglobin or spherocytosis. It is caused by glucose phosphate isomerase deficiency. Severe GPI deficiency can be associated with hydrops fetalis, immediate neonatal death and neurological impairment. SIMILARITY: Belongs to the GPI family.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
