| UniProt functional annotation for P09104 | |||
| UniProt code: P09104. |
| Organism: | Homo sapiens (Human). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo. | |
| Function: | Has neurotrophic and neuroprotective properties on a broad spectrum of central nervous system (CNS) neurons. Binds, in a calcium- dependent manner, to cultured neocortical neurons and promotes cell survival (By similarity). {ECO:0000250}. | |
| Catalytic activity: | Reaction=(2R)-2-phosphoglycerate = H2O + phosphoenolpyruvate; Xref=Rhea:RHEA:10164, ChEBI:CHEBI:15377, ChEBI:CHEBI:58289, ChEBI:CHEBI:58702; EC=4.2.1.11; | |
| Cofactor: | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Mg(2+) is required for catalysis and for stabilizing the dimer.; | |
| Pathway: | Carbohydrate degradation; glycolysis; pyruvate from D- glyceraldehyde 3-phosphate: step 4/5. | |
| Subunit: | Mammalian enolase is composed of 3 isozyme subunits, alpha, beta and gamma, which can form homodimers or heterodimers which are cell-type and development-specific. {ECO:0000269|PubMed:15289101}. | |
| Subcellular location: | Cytoplasm {ECO:0000250}. Cell membrane {ECO:0000250}. Note=Can translocate to the plasma membrane in either the homodimeric (alpha/alpha) or heterodimeric (alpha/gamma) form. {ECO:0000250}. | |
| Tissue specificity: | The alpha/alpha homodimer is expressed in embryo and in most adult tissues. The alpha/beta heterodimer and the beta/beta homodimer are found in striated muscle, and the alpha/gamma heterodimer and the gamma/gamma homodimer in neurons. | |
| Developmental stage: | During ontogenesis, there is a transition from the alpha/alpha homodimer to the alpha/beta heterodimer in striated muscle cells, and to the alpha/gamma heterodimer in nerve cells. | |
| Induction: | Levels of ENO2 increase dramatically in cardiovascular accidents, cerebral trauma, brain tumors and Creutzfeldt-Jakob disease. | |
| Similarity: | Belongs to the enolase family. {ECO:0000305}. | |
| Sequence caution: | Sequence=AAA52388.1; Type=Erroneous initiation; Evidence={ECO:0000305}; | |
