Predicted to enable nucleoside diphosphate kinase activity; thymidylate kinase activity; and uridylate kinase activity. Involved in several processes, including pyrimidine deoxyribonucleotide biosynthetic process; response to cadmium ion; and response to estrogen. Located in mitochondrial intermembrane space and mitochondrial matrix. Orthologous to human DTYMK (deoxythymidylate kinase). [provided by Alliance of Genome Resources, Apr 2022]
