The ENO1 protein converts 2-phosphoglycerate to phosphoenolpyruvate and is involved in growth control, hypoxia tolerance, and allergic responses. It acts as a receptor and activator of plasminogen, stimulating immunoglobulin production. ENO1 binds to the myc promoter as a transcriptional repressor and may function as a tumor suppressor. Enolase 1/ENO1 Protein, Human (His, solution) is the recombinant human-derived ENO1, expressed by E. coli , with C-His labeled tag.
