ENO1

(Enolase 1)

 

  • Alias                                 (According to NCBI)

 

  • NNE non-neural enolase
  • PPH  phosphopyruvate hydratase
  • MPB1 MYC promoter-binding protein 1
  • MBPB1
  • ENO1L1
  • 2-phospho-D-glycerate hydro-lyase
  • C-myc promotor binding protein
  • alpha enolase like 1
  • tau-crystallin
  • plasminogen binding protein
  • Multifunctional enzyme that, as well as its role in glycolysis, plays a part in various processes such as growth control, hypoxia tolerance and allergic responses. May also function in the intravascular and pericellular fibrinolytic system due to its ability to serve as a receptor and activator of plasminogen on the cell surface of several cell-types such as leukocytes and neurons.
  • Isoform, MBP1 binds to the c-myc promoter and acts as a transcriptional repressor. May be a tumor suppressor.
  • Location: 1p36.3-p36.2
  • Size: 17718  bp
  • exons: 11
  • DNA sequence (Human): NC_000001

  • CGH (1p36.2):  Losses (%) -6.3   Gain (%)  0.0   Amplifications  0.0

  • Mutations and SNPs (According to HGMD and SNP)

 

 

  • m-RNA                       (According to NCBI and CGAP)

 

  • Size: 434 amino acids;  47169 Da
  • Catalytic activity: phosphopyruvate hydtratase activity. 2 Phospho D Glycerate = Phosphoenolpyruvate + H2o.

                                      The Chemical Reactions and Pathways Resulting in the Breakdown of a Monosaccharide

                                      (generally Glucose) Into Pyruvate with the Concomitant Production of a Small Amount of Atp.          

                                      Pyruvate May Be Converted to Ethanol Lactate or Other Small Molecules or Fed Into the Tca Cycle. 

                                      Chain B

  • COFACTOR: Magnesium. Required for catalysis and for stabilizing the dimer

  • Subcellular location: Cytoplasm. Cell membrane. Cytoplasm, myofibril, sarcomere, M-band. Note=Can translocate to the plasma membrane in either the homodimeric (alpha/alpha) or heterodimeric (alpha/gamma) form. ENO1 is localized to the M-band.

          Isoform MBP-1: Nucleus.

  • Protein domains
