Function

[ENOA_HUMAN] Multifunctional enzyme that, as well as its role in glycolysis, plays a part in various processes such as growth control, hypoxia tolerance and allergic responses. 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. Stimulates immunoglobulin production.^[1] ^[2] ^[3] ^[4] ^[5] MBP1 binds to the myc promoter and acts as a transcriptional repressor. May be a tumor suppressor.^[6] ^[7] ^[8] ^[9] ^[10]

Publication Abstract from PubMed

Aside from its enzymatic function in the glycolytic pathway, alpha-enolase (ENO1) has been implicated in numerous diseases, including metastatic cancer, autoimmune disorders, ischaemia and bacterial infection. The disease-related roles of ENO1 are mostly attributed to its immunogenic capacity, DNA-binding ability and plasmin(ogen) receptor function, which are significantly affected by its three-dimensional structure and surface properties, rather than its enzymatic activity. Here, the crystal structure of human ENO1 (hENO1) is presented at 2.2 A resolution. Despite its high sequence similarity to other enolases, the hENO1 structure exhibits distinct surface properties, explaining its various activities, including plasmin(ogen) and DNA binding.
