Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

|---|---|
| Other Names | Thymidine kinase 2, mitochondrial, Mt-TK, TK2 |
| Target/Specificity | This Thymidine Kinase 2 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 8-38 amino acids from the N-terminal region of human Thymidine Kinase 2. |
| Dilution | WB~~1:1000 |
| Format | Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is prepared by Saturated Ammonium Sulfate (SAS) precipitation followed by dialysis against PBS. |
| Storage | Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles. |
| Precautions | Thymidine Kinase 2 Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures. |
| Name | TK2 {ECO:0000303|PubMed:9989599, ECO:0000312|HGNC:HGNC:11831} |
|---|---|
| Function | Phosphorylates thymidine, deoxycytidine, and deoxyuridine in the mitochondrial matrix (PubMed:9989599, PubMed:11687801). In non- replicating cells, where cytosolic dNTP synthesis is down-regulated, mtDNA synthesis depends solely on TK2 and DGUOK (PubMed:9989599). Widely used as target of antiviral and chemotherapeutic agents (PubMed:9989599). |
| Cellular Location | Mitochondrion. |
| Tissue Location | Predominantly expressed in liver, pancreas, muscle, and brain. |

Background
Thymidine kinase-2 (TK2) is a deoxyribonucleoside kinase that phosphorylates thymidine, deoxycytidine, and deoxyuridine, and also phosphorylates antiviral and anticancer nucleoside analogs. Both recombinant and native forms of the enzyme have broad substrate specificity and complex kinetics, suggesting that it may play a role in the activation of chemotherapeutic nucleoside analogs. The highest levels of expression are observed in testis and ovary. The main supply of deoxyribonucleotides (dNTPs) for mitochondrial DNA synthesis comes from the salvage pathway initiated by deoxyguanosine kinase (DGK) and TK2. The association of mitochondrial DNA depletion with mutations in the genes encoding these 2 kinases suggests that the salvage pathway enzymes are involved in the maintenance of balanced mitochondrial dNTP pools.
