Dihydrofolate reductase (DHFR) is encoded by the gene mapped to human chromosome 5q14. The encoded protein belongs to reductase family of enzymes. It is ubiquitously expressed in all organisms. DHFR is characterized with an α/β fold with a central 8-stranded sheet, flanked by four α helices.
Dihydrofolate reductase converts dihydrofolate into tetrahydrofolate, a methyl group shuttle required for the de novo synthesis of purines, thymidylic acid, and certain amino acids. While the functional dihydrofolate reductase gene has been mapped to chromosome 5, multiple intronless processed pseudogenes or dihydrofolate reductase-like genes have been identified on separate chromosomes. Dihydrofolate reductase deficiency has been linked to megaloblastic anemia. (provided by RefSeq)

Dihydrofolate reductase (DHFR) is a folate-metabolizing enzyme that catalyzes nicotinamide adenine dinucleotide phosphate (NADPH)-dependent reduction of dihydrofolate (DHF) to tetrahydrofolate (THF), as well as folic acid to DHF. The encoded protein is implicated in regulation of intracellular folate homeostasis and it acts as a key target for cytostatic drugs. Genetic variations in the gene is associated with the development of various neurologic diseases.

De novo thymidylate synthesis is a crucial pathway for normal and cancer cells. Deoxythymidine monophosphate (dTMP) is synthesized by the combined action of three enzymes: serine hydroxymethyltransferase (SHMT1), dihydrofolate reductase (DHFR) and thymidylate synthase (TYMS), with the latter two being targets
