背景
This gene encodes a member of the glucose phosphate isomerase protein family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. In the cytoplasm, the gene product functions as a glycolytic enzyme (glucose-6-phosphate isomerase) that interconverts glucose-6-phosphate and fructose-6-phosphate. Extracellularly, the encoded protein (also referred to as neuroleukin) functions as a neurotrophic factor that promotes survival of skeletal motor neurons and sensory neurons, and as a lymphokine that induces immunoglobulin secretion. The encoded protein is also referred to as autocrine motility factor based on an additional function as a tumor-secreted cytokine and angiogenic factor. Defects in this gene are the cause of nonspherocytic hemolytic anemia and a severe enzyme deficiency can be associated with hydrops fetalis
功能
catalytic activity:D-glucose 6-phosphate = D-fructose 6-phosphate.,disease:Defects in GPI are a cause of hereditary nonspherocytic hemolytic anemia (HA) [MIM:172400]. Severe GPI deficiency can be associated with hydrops fetalis, immediate neonatal death and neurological impairment.,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.,online information:Phosphoglucose isomerase entry,online information:The Singapore human mutation and polymorphism database,pathway:Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 2/4.,PTM:Phosphorylation at Ser-185 by CK2 has been shown to decrease enzymatic activity and may contribute to s
