| Post Translational Modifications | Phosphorylated on Ser-13 in mitosis. Phosphorylation of Ser-13 by CDK1 during mitosis reduces homotetramerization and catalytic efficiency when DNA replication is complete and intracellular TK1 is still present at a high level. Polyubiquitinated. Postmitosis, ubiquitination leads to proteasomal degradation. The KEN box sequence located at the C-terminal region targets for degradation by the anaphase promoting complex (APC/C) activated and rate-limited by FZR1. |
| Function | Cell-cycle-regulated enzyme of importance in nucleotide metabolism. Catalyzes the first enzymatic step in the salvage pathway converting thymidine into thymidine monophosphate. Transcriptional regulation limits expression to the S phase of the cell cycle and transient expression coincides with the oscillation in the intracellular dTTP concentration (Probable). Also important for the activation of anticancer and antiviral nucleoside analog prodrugs such as 1-b-d-arabinofuranosylcytosine (AraC) and 3c-azido-3c-deoxythymidine (AZT). |
