  • Target

    • Function

      Glycolytic enzyme that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP. Stimulates POU5F1-mediated transcriptional activation. Plays a general role in caspase independent cell death of tumor cells. The ratio betwween the highly active tetrameric form and nearly inactive dimeric form determines whether glucose carbons are channeled to biosynthetic processes or used for glycolytic ATP production. The transition between the 2 forms contributes to the control of glycolysis and is important for tumor cell proliferation and survival.
    • Tissue specificity

      Specifically expressed in proliferating cells, such as embryonic stem cells, embryonic carcinoma cells, as well as cancer cells.
    • Pathway

      Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 5/5.
    • Sequence similarities

      Belongs to the pyruvate kinase family.
    • Post-translational

      Under hypoxia, hydroxylated by EGLN3.
      Acetylation at Lys-305 is stimulated by high glucose concentration, it decreases enzyme activity and promotes its lysosomal-dependent degradation via chaperone-mediated autophagy.
      FGFR1-dependent tyrosine phosphorylation is reduced by interaction with TRIM35.
    • Cellular localization

      Cytoplasm. Nucleus. Translocates to the nucleus in response to different apoptotic stimuli. Nuclear translocation is sufficient to induce cell death that is caspase independent, isoform-specific and independent of its enzymatic activity.

    • This ICC data was generated using the same anti-PKM antibody clone, EPR10138(B), in a different buffer formulation (cat# ab150377).

      Immunocytochemistry/Immunofluorescence analysis of HeLa (human cervix adenocarcinoma) labelling PKM with purified ab150377 at 1/500. Cells were fixed with 4% PFA and permeabilized with 0.1% Triton X-100. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody (Ab150077). Nuclei counterstained with DAPI (blue).

      Control: PBS only
