Anti-DHFRP4 antibodies enable researchers to detect and measure the DHFRP4 antigen in biological samples. This target is a reported synonym of the DHFR2 gene, which encodes dihydrofolate reductase 2. This protein is known to function in metabolic processes, among other biological roles. The human version of DHFRP4 has a canonical amino acid length of 187 residues and a protein mass of 21.6 kilodaltons. It is reported to be localized in the mitochondria of cells. DHFRP4 is a member of the Dihydrofolate reductase protein family.
