| 734402 | Folr1 | folate receptor alpha | Enables folic acid receptor activity. Involved in several processes, including circulatory system development; nervous system development; and regulation of signal transduction. Acts upstream of or within folic acid metabolic process. Is active in plasma membrane. Is expressed in several structures, including brain; early conceptus; genitourinary system; gut; and retina. Human ortholog(s) of this gene implicated in cerebral folate receptor alpha deficiency. Orthologous to human FOLR1 (folate receptor alpha).

| 1346305 | FOLR1 | folate receptor alpha | The protein encoded by this gene is a member of the folate receptor family. Members of this gene family bind folic acid and its reduced derivatives, and transport 5-methyltetrahydrofolate into cells. This gene product is a secreted protein that either anchors to membranes via a glycosyl-phosphatidyl inositol linkage or exists in a soluble form. Mutations in this gene have been associated with neurodegeneration due to cerebral folate transport deficiency. Due to the presence of two promoters, multiple transcription start sites, and alternative splicing, multiple transcript variants encoding the same protein have been found for this gene.

| 1318329 | FOLR2 | folate receptor beta | The protein encoded by this gene is a member of the folate receptor (FOLR) family, and these genes exist in a cluster on chromosome 11. Members of this gene family have a high affinity for folic acid and for several reduced folic acid derivatives, and they mediate delivery of 5-methyltetrahydrofolat e to the interior of cells. This protein has a 68% and 79% sequence homology with the FOLR1 and FOLR3 proteins, respectively. Although this protein was originally thought to be specific to placenta, it can also exist in other tissues, and it may play a role in the transport of methotrexate in synovial macrophages in rheumatoid arthritis patients. Multiple transcript variants that encode the same protein have been found for this gene.
