Cloning of the cDNA and chromosome localization of the gene for human thymidine kinase 2.
Human thymidine kinase 2 (TK2) is a deoxyribonucleoside kinase that phosphorylates thymidine, deoxycytidine, and deoxyuridine. The enzyme also phosphorylates anti-viral and anti-cancer nucleoside analogs. We have identified an expressed sequence tag cDNA that encoded a 27.5-kDa protein approximately 30% similar to the human deoxycytidine kinase and deoxyguanosine kinase. The protein was express...
متن کاملGenetic Control of Mitochondrial Thymidine Kinase in Human-mouse and Monkey-mouse Somatic Cell Hybrids
Distinctive thymidine (dT) kinase molecular forms are present in mouse, human, and monkey mitochondria. Disk polyacrylamide gel electrophoresis (disk PAGE) analyses have shown that the mitochondrial-specific dT kinases differ from cytosol dT kinases in relative electrophoretic mobilities (Rm). Furthermore, the mouse mitochondrial dT kinase differs in Rm value from primate mitochondrial dT kinas...
متن کاملMolecular cloning of mouse placental lactogen cDNA.
We have isolated a cDNA clone for the 23-kDa mouse placental lactogen II (mPL-II) from a phage lambda gt11 expression library containing cDNA synthesized from BALB/c placental RNA. Translation in vitro of placental mRNA selected by hybridization to the mPL-II cDNA clones yields a 26-kDa polypeptide that is the size of the expected precursor protein and that is immunoprecipitated with anti-mPL-I...
متن کاملCloning and expression of human deoxyguanosine kinase cDNA.
A human cDNA sequence homologous to human deoxycytidine kinase (dCK; EC 2.7.1.74) was identified in the GenBank sequence data base. The longest open reading frame encoded a protein that was 48% identical to dCK at the amino acid level. The cDNA was expressed in Escherichia coli and shown to encode a protein with the same substrate specificity as described for the mitochondrial deoxyguanosine ki...
متن کاملCloning and expression of human deoxycytidine kinase cDNA.
Deoxycytidine (dCyd) kinase is required for the phosphorylation of several deoxyribonucleosides and certain nucleoside analogs widely employed as antiviral and chemotherapeutic agents. Detailed analysis of this enzyme has been limited, however, by its low abundance and instability. Using oligonucleotides based on primary amino acid sequence derived from purified dCyd kinase, we have screened T-...
