 2.1.1.67 | evolution |
Callithrix jacchus thiopurine S-methyltransferase (TPMT) is phylogenetically closer to other primate orthologs than to its pig, dog, rabbit, or rodent orthologs |

 2.1.1.67 | evolution |
Callithrix jacchus thiopurine S-methyltransferase (TPMT) is phylogenetically closer to other primate orthologs than to its pig, dog, rabbit, or rodent orthologs. Callithrix jacchus and human TPMT are similar at the molecular level |

 2.1.1.67 | malfunction |
intermediate and low enzyme activity may lead to leukopenia following thiopurine treatment |
733706 |
 2.1.1.67 | malfunction |
when thiopurine methyltransferase protein activity is low a greater degree of cytotoxicity and DNA damage can occur after thioguanine exposure |
720847 |
 2.1.1.67 | metabolism |
thiopurine drugs, azathioprine, mercaptopurine, and thioguanine, are widely used in the treatment of several malignant and nonmalignant diseases. Patients with low-activity variants of thiopurine S-methyltransferase can be affected by pronounced pharmacologic effects when receiving thiopurine medications |
778459 |
 2.1.1.67 | more |
a method used to determine thiopurine S-methyltransferase activity by measuring 6-MMP by liquid chromatography-tandem mass spectrometry while employing 6-methylmercaptopurine-d3 as an internal standard |
778459 |
 2.1.1.67 | more |
the enzyme plays roles in the metabolism of widely used anticancer and anti-inflammatory drugs |

 2.1.1.67 | physiological function |
both thiopurine S-methyltransferase (TPMT) and indolethylamine N-methyltransferase (INMT) cooperatively contributed to the trimethylselenonium ion production, enabling urinary excretion of Se and maintenance of homeostasis of this essential yet highly toxic trace element. Thus, TPMT and INMT can be recognized as selenium methyltransferases |
777027 |
 2.1.1.67 | physiological function |
thiopurine S-methyltransferase and indolethylamine N-methyltransferase are cooperatively responsible for the detoxification of Tellurium oxyanions through methylation to form trimethyltelluronium ions |
