Clinical Significance:
Enolase is a glycolytic enzyme catalyzing the reaction pathway between 2-phosphoglycerate and phosphoenol pyruvate. In mammals, enolase molecules are dimers composed of three distinct subunits (α, β and γ). The alpha-alpha dimer (R enolase) is the target for Neuron Specific Enolase, and is found in neural tissue, neuroendocrine cells and their tumors. However, the antibody also cross-reacts with the alpha-gamma heterodimer, which is present in a wide range of non-neuroendocrine cells, including smooth muscle, myoepithelial cells, platelets, lymphocytes, cells of the loop of enle, some carcinomas of the kidney, breast and ovary, and in seminomas.
