This family includes the folate receptor which binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate to the interior of cells. These proteins are attached to the membrane by a GPI-anchor. The proteins contain 16 conserved cysteines that form eight disulphide bridges.	Domain
