Folate receptor 1 (Folate receptor alpha, FOLR1) is a protein that in humans is encoded by the FOLR1 gene.[5][6]
The protein encoded by this gene is a member of the folate receptor (FOLR) family. Members of this family have a high affinity for folic acid and for several reduced folic acid derivatives, and mediate delivery of 5-methyltetrahydrofolate to the interior of cells.
