Also known as: NSE; RNEN3
Summary: Enables enzyme binding activity; identical protein binding activity; and phosphopyruvate hydratase activity. Involved in glucose metabolic process; response to estradiol; and response to xenobiotic stimulus. Located in several cellular components, including growth cone; membrane raft; and synaptic membrane. Part of phosphopyruvate hydratase complex. Biomarker of Parkinsonism; toxic shock syndrome; and visual epilepsy. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to human ENO2 (enolase 2). [provided by Alliance of Genome Resources, Dec 2024]
Annotation information: Note: LOC100911625 appears to be a duplicate placement of Eno2 (GeneID: 24334) on Rnor_6.0 (Annot. Release 105) that is absent from Rn_Celera and is not supported by syntenic regions in mouse and human. BLAST analysis of the underlying component AABR07066868.1 against the rat genome shows high sequence identity (88% coverage, 99% identity) with part of NC_005103.4 on which Eno2 is annotated. Annotation of Eno2 at this location on Rnor_6.0 is supported by annotation on Rn_Celera and synteny with mouse and human. [14 Apr 2021]
Expression: Biased expression in Brain (RPKM 1706.0) and Uterus (RPKM 89.6) See more

gamma-enolase may signal and correlate lung tissue damage well before obvious physical pathological tissue damage and might be a candidate diagnostic and/or prognostic marker.
Title: Gamma-enolase predicts lung damage in severe acute pancreatitis-induced acute lung injury.
Study analyzed the regions that regulate the promoter strength and cellular specificity of the 1.8 kb rNSE promoter in the cerebellum in vivo. The rNSE promoter was divided into three regions (A, B, and C). Our results showed that region C was indispensable for the promoter activity in mouse cerebellum and served as an interneuron-predominant basal promoter.
Title: Viral Vector-Based Evaluation of Regulatory Regions in the Neuron-Specific Enolase (NSE) Promoter in Mouse Cerebellum In Vivo.
Study showed that the NSE promoter was activated in astrocytes, including Bergmann glia (BG), but not Purkinje cells (PCs), in the traumatic region of the cerebellar cortex. This PC to BG switch was associated with local microglial invasion.
Title: Inflammation-induced reversible switch of the neuron-specific enolase promoter from Purkinje neurons to Bergmann glia.
Hyperglycemia may impair mitochondrial function and alter glycolysis in glomerular epithelial cells by down-regulating the expression of ATP synthase beta subunit and enolase 2.
Title: Hyperglycemia decreases the expression of ATP synthase β subunit and enolase 2 in glomerular epithelial cells.
Data show statistically significant altered levels of Tpi1 and alteration of Hk1, Aldoc, Pgam1 and Gapdh with borderline significance in phencyclidine (PCP) rats compared to controls.
Title: The application of selective reaction monitoring confirms dysregulation of glycolysis in a preclinical model of schizophrenia.
NSE and Tau are abundantly expressed in the brain cells and MSC-derived neurocyte-like cells.
Title: Effect of neuronal induction on NSE, Tau, and Oct4 promoter methylation in bone marrow mesenchymal stem cells.
The enolase activity, coupled with lactate dehydrogenase, was higher during the light period than that in the dark.
Title: Circadian rhythm of enolase in suprachiasmatic nucleus depends on mitochondrial function.

Title: Expression of neuron-specific enolase in irradiated salivary glands of the rat: a pilot study.
Data suggets that neuregulin-1beta inhibits the activation of MMP-9 and development of inflammation, enhances the activity of NSE, improves the microenvironment of neuron survivals, and delays the phase of irreversible neuron necrosis.
Title: Effects of neuregulin on expression of MMP-9 and NSE in brain of ischemia/reperfusion rat.
Isozymes alpha- and gamma-enolases were identified as targets for cathepsin X.
Title: Cathepsin X cleaves the C-terminal dipeptide of alpha- and gamma-enolase and impairs survival and neuritogenesis of neuronal cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
