MTHFD2 (Methylenetetrahydrofolate Dehydrogenase 2): MTHFD2 is an enzyme that plays a vital role in the mitochondrial one-carbon metabolic pathway, crucial for nucleotide biosynthesis, methylation reactions, and amino acid homeostasis. This enzyme is highly expressed in rapidly dividing cells, including cancer cells, where it contributes to the synthesis of purines and thymidylate, essential for DNA replication and repair. MTHFD2's involvement in cellular metabolism and proliferation highlights its importance in developmental processes and cellular growth. Due to its pivotal role in supporting the metabolic demands of tumor growth and its limited expression in normal adult tissues, MTHFD2 has emerged as a potential...
