Application

EC Number Application Comment Organism
2.1.1.45 medicine thymidylate synthase is an important target for cancer chemotherapy Homo sapiens

Protein Variants

EC Number Protein Variants Comment Organism
2.1.1.45 additional information targeting of mRNA with antisense oligodeoxynucleotides, complementary to the translation start site, the coding region, and the 3' untranslated region. In response to treatment with translation start site-targeting antisense oligodeoxynucleotide 791, thymidylate synthase gene transcription in HeLa cells is increased by 70%. Increased thymidylate synthase gene transcription and nuclear thymidylate synthase RNA do not elevate levels of total cellular thymidylate synthase mRNA, but do increase thymidylate synthase protein activity by 35% and thymidylate synthase protein level by 150%. Increased thymidylate synthase protein activity and level do not alter proliferation rate or sensitivity to thymidylate synthase-targeting drugs Homo sapiens
