Thymidylate Synthase

Thymidylate synthase (TS) is an E2F1-regulated enzyme that is essential for DNA synthesis and repair. Thymidylate synthase is an essential S phase enzyme required for DNA synthesis. Thymidylate synthase plays a central role in the biosynthesis of thymidylate, an essential precursor for DNA synthesis.

Thymidylate synthase catalyzes the reductive methylation of 2′-deoxyuridine 5-monophosphate (dUMP) by transfer of a methylene group from a cofactor, CH2H4 folate, to generate deoxythymidine-5′-monophoshate (dTMP). dTMP is further phosphorylated to the triphosphate state (dTTP), which is a direct precursor for DNA synthesis. Since the TS catalyzed reaction is the sole intracellular de novo source of dTMP, the inhibition of TS results in the cessation of cellular proliferation and growth.

Thymidylate synthase protein and mRNA levels are elevated in many human cancers, and high TS levels have been correlated with poor prognosis in patients with colorectal, breast, cervical, bladder, kidney, and non-small cell lung cancers.
