KITM

Thymidine kinase 2, mitochondrial; Isoform 6 of Thymidine kinase 2, mitochondrial; Isoform 2 of Thymidine kinase 2, mitochondrial

Phosphorylates thymidine, deoxycytidine, and deoxyuridine in the mitochondrial matrix (PubMed:11687801, PubMed:9989599). 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).
