Scientific background

Solute Carrier Transporter 19A1, (SLC19A1, RFC1) is a high-capacity, bi-directional transporter of 5-methyl-tetrahydrofolate and thiamine monophosphate1,2. SLC19A1 is characterized by 12 transmembrane domains (TMDs) and cytoplasm oriented N- and C-termini3.

Folate is a major nutrient that supports important physiological functions such as DNA synthesis, cell division and substrate methylation. Low folate levels caused by suboptimal intake, transport and cellular utilization of folate, is a risk factor for diseases such as spina bifida, cardiovascular diseases and certain types of cancer1.

SLC19A1 is the main folate transporter and it plays a critical role in folate uptake and homeostasis in mammalian cells4. High SLC19A1 transcript levels are detected in liver and placenta, with appreciable levels in other tissues, including kidney, lung, bone marrow, intestine, brain, and portions of the central nervous system5.

SLC19A1 is also involved in the uptake of Methotrexate (MTX); one of the leading chemotherapeutic agents with the best demonstrated efficacies against childhood acute lymphoblastic leukemia and hence malfunction of this transporter also effects the efficiency of this type of cancer treatment6.
