Enolase 2
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
Neuron-specific enolase (NSE) immunostaining of a cerebellar hemangioblastoma.
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]
gollark: Communism detected. Deploying the [REDACT].
gollark: Also, why is this not concurrent? It should be concurrent.
gollark: Have you tried on ARM, for arbitrary purposes?
gollark: ABR is now up due to unbee unincursions.
gollark: Unfortunately, ABR is now unavailable to bee incursions.
