Function

Cell-cycle-regulated enzyme of importance in nucleotide metabolism (PubMed:9575153). Catalyzes the first enzymatic step in the salvage pathway converting thymidine into thymidine monophosphate (PubMed:22385435). 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) (PubMed:22385435).

Activity summary

Thymidine Kinase 1 (TK1) also known as Thymidine Kinase isoform A is an enzyme involved in the phosphorylation of thymidine into thymidine monophosphate an important component in DNA synthesis. TK1 has a molecular weight of approximately 25 kDa. It is predominantly expressed in proliferating cells with expression levels peaking during the S phase of the cell cycle. You often find TK1 in tissues with high cell division rates like bone marrow and lymphatic tissues.

Biological function summary

This enzyme is critical for DNA replication and repair by providing deoxythymidine triphosphate (dTTP) a deoxynucleoside triphosphate. TK1 operates as a monomer but can form a tetrameric complex in its active state which enhances its affinity for substrates. TK1 can process various substrates including thymidine and thymidine analogs such as 5-bromo-2'-deoxyuridine (BrdU) and EdU. These substrates are vital in molecular biology as they help in measuring DNA synthesis in cell proliferation studies.

Pathways

The function of TK1 is central to the salvage pathway of nucleotide synthesis. This pathway allows recycling of thymidine from degraded DNA which is particularly important for rapidly dividing cells that need to ensure a sufficient supply of nucleotides. TK1 acts alongside other enzymes such as thymidylate synthase and ribonucleotide reductase to maintain nucleotide balance within the cell ensuring proper DNA synthesis and cellular proliferation.

Associated diseases and disorders

TK1 levels often increase in cancerous tissues due to their elevated cell proliferation rates. Serum TK1 is a biomarker for various cancers like leukemia and breast cancer. Studies show a correlation between high TK1 activity and tumor aggressiveness and progression. Additionally interactions of TK1 with the protein p53 a tumor suppressor show that defects in TK1 regulation can contribute to genomic instability highlighting its role in oncogenesis.

    Overlay histogram showing HeLa cells stained with ab208998 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab208998, 1/5000 dilution) for 30 min at 22°C.

    Isotype control antibody (black line) was rabbit IgG (monoclonal) Phycoerythrin (PE Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

    Acquisition of >5,000 events were collected using a 50mW Yellow-Green laser (561nm) and 586/15 bandpass filter.

The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab208998 at 1/100 dilution (Pseudocolored in green) and Alexa Fluor® 647 Anti-Tubulin antibody [YOL1/34] - Microtubule Marker ab195884, Rat monoclonal to Tubulin (Alexa Fluor® 647), at 1/250 dilution (shown in red).
