Folate transporter 1 is a protein which in humans is encoded by the SLC19A1 gene.[5]
Function
Transport of folate compounds into mammalian cells can occur via receptor-mediated (see folate receptor 1) or carrier-mediated mechanisms. A functional coordination between these 2 mechanisms has been proposed to be the method of folate uptake in certain cell types. Methotrexate (MTX) is an antifolate chemotherapeutic agent that is actively transported by the carrier-mediated uptake system. RFC1 plays a role in maintaining intracellular concentrations of folate.[6] SLC19A1 has also been shown to transport the immune second messenger 2'3'-cGAMP.[7]
Clinical significance
Individuals carrying a specific polymorphism of SLC19A1 (c.80GG) have lower levels of folate.[8] Other studies have also shown that individuals carrying the c.80AA polymorphism who are treated with methotrexate have higher levels of this anti-folate chemotherapeutic agent. Personalized dosing of the drug depending on the patient's genotype may therefore be required.
