Gene: Tk2 (thymidine kinase 2) Rattus norvegicus
Analyze
Symbol: Tk2
Name: thymidine kinase 2
RGD ID: 1309279
Description: Enables deoxycytidine kinase activity and thymidine kinase activity. Involved in deoxycytidine metabolic process and thymidine metabolic process. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in autosomal recessive progressive external ophthalmoplegia with mitochondrial DNA deletions 3 and mitochondrial DNA depletion syndrome 2. Orthologous to human TK2 (thymidine kinase 2); PARTICIPATES IN pyrimidine metabolic pathway; INTERACTS WITH 2,4-dinitrotoluene; 2,6-dinitrotoluene; acrylamide.
Type: protein-coding
RefSeq Status: PROVISIONAL
Previously known as: LOC291824; thymidine kinase 2, mitochondrial
