Gamma-enolase, also known as enolase 2 (ENO2) or neuron specific enolase (NSE), is an enzyme that in humans is encoded by the ENO2 gene.^[5][6] Gamma-enolase is a phosphopyruvate hydratase.

Gamma-enolase is one of the three enolase isoenzymes found in mammals. This isoenzyme, a homodimer, is found in mature neurons and cells of neuronal origin. A switch from alpha enolase to gamma enolase occurs in neural tissue during development in rats and primates.^[5]

Utility[edit]

Detection of NSE with antibodies can be used to identify neuronal cells and cells with neuroendocrine differentiation. NSE is produced by small-cell carcinomas, which are neuroendocrine in origin. NSE is therefore a useful tumor marker for distinguishing small-cell carcinomas from other tumors.^[7]
