This gene encodes alpha-enolase, one of three enolase isoenzymes found in mammals. Each isoenzyme is a homodimer composed of 2 alpha, 2 gamma, or 2 beta subunits, and functions as a glycolytic enzyme. Alpha-enolase in addition, functions as a structural lens protein (tau-crystallin) in the monomeric form. Alternative splicing of this gene results in a shorter isoform that has been shown to bind to the c-myc promoter and function as a tumor suppressor. Several pseudogenes have been identified, including one on the long arm of chromosome 1. Alpha-enolase has also been identified as an autoantigen in Hashimoto encephalopathy.,ENO1,ENO1L1,HEL-S-17,MPB1,NNE,PPH,enolase 1,Epigenetics & Nuclear Signaling,Transcription Factors,RNA Binding,Cancer,Tumor suppressors,Signal Transduction,Endocrine & Metabolism,Carbohydrate metabolism,ENO1
