  • Function
    Catalyzes the S-methylation of thiopurine drugs such as 6-mercaptopurine.
  • Involvement in disease
    Defects in TPMT are the cause of thiopurine S-methyltransferase deficiency (TPMT deficiency) [MIM:610460]. TPMT is an enzyme involved in the normal metabolic inactivation of thiopurine drugs. These drugs are generally used as immunosupressants or cytotoxic drugs and are prescribed for a variety of clinical conditions including leukemia, autoimmune disease and organ transplantation. Patients with intermediate or no TPMT activity are at risk of toxicity after receiving standard doses of thiopurine drugs and it is shown that inter-individual differences in response to these drugs are largely determined by genetic variation at the TPMT locus.

  • Predicted band size : 28 kDa

    Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
    Lane 2: TPMT knockout HAP1 whole cell lysate (20 µg)
    Lane 3: HepG2 whole cell lysate (20 µg)

    Lanes 1 - 3: Merged signal (red and green). Green - ab122984 observed at 28 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab122984 was shown to recognize TPMT in wild-type HAP1 cells as signal was lost at the expected MW in TPMT knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and TPMT knockout samples were subjected to SDS-PAGE. Ab122984 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

    goat anti-mouse secondary antibody conjugated to HRP
    Developed using the ECL technique

    Predicted band size : 28 kDa

  • Predicted band size : 28 kDa

    The Recombinant Protein (50ng) and Cell lysates (40ug) were resolved by SDS-PAGE, transferred to PVDF membrane and probed with anti-human TPMT antibody (1:1000). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and an ECL detection system.

    Lane 1 : Recombinant Protein
    Lane 2 : HepG2 cell lysate

  • Immunocytochemistry/Immunofluorescence analysis of U87MG cells labelling TPMT with ab122984 at 1/100. An Alexa Fluor® 488-conjugated goat anti-mouse IgG was used as the secondary antibody. DAPI (blue) was used as the nuclear counterstain.

  • Flow Cytometry analysis of U87MG cells labelling TPMT with ab122984, staining at 2-5 µg/1x106 cells (red). A 488-conjugated goat anti-mouse IgG was used as the secondary antibody. Black - Isotype control, mouse IgG.
