Protein Name: Alpha-enolase

UniprotKB/SwissProt ID: P06733 (P06733)

Gene Name: ENO1

Organism: Homo sapiens (Human)

Function: Glycolytic enzyme the catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate (PubMed:1369209, PubMed:29775581). In addition to glycolysis, involved in various processes such as growth control, hypoxia tolerance and allergic responses (PubMed:10802057, PubMed:12666133, PubMed:2005901, PubMed:29775581). May also function in the intravascular and pericellular fibrinolytic system due to its ability to serve as a receptor and activator of plasminogen on the cell surface of several cell-types such as leukocytes and neurons (PubMed:12666133). Stimulates immunoglobulin production (PubMed:1369209) Binds to the myc promoter and acts as a transcriptional repressor. May be a tumor suppressor

Protein Subcellular Localization: Cytoplasm. Cell membrane. Cytoplasm, myofibril, sarcomere, M line. Nucleus
