cytosolic thymidine kinase. Phosphorylated during mitosis. Its enzymatic activity is high in proliferating cells and peaks during the S-phase of the cell cycle; it is very low in resting cells. Note: This description may include information from UniProtKB.
Protein type: Kinase, other; EC 184.108.40.206; Xenobiotic Metabolism - drug metabolism - other enzymes; Nucleotide Metabolism - pyrimidine
Cellular Component: cytosol
Molecular Function: identical protein binding; nucleoside kinase activity; zinc ion binding; thymidine kinase activity; ATP binding
