Background: FOLR2

Folate Receptor 2 (FOLR2), also known as Folate Receptor beta, is a 38 kDa protein that mediates the cellular uptake of folic acid and reduced folates. Dietary folates are required for many key metabolic processes including nucleotide and methionine synthesis, the interconversion of glycine and serine, and histidine breakdown (1, 2). Mature FOLR2 is an N-glycosylated protein that is anchored to the cell surface by a GPI linkage (3, 4). Human FOLR2 shares 83% amino acid sequence identity with mouse and rat FOLR2. FOLR2 is predominantly expressed in placenta, cells of the neutrophilic lineage, and some CD34+ hematopoietic progenitor cells (4‑6). It is up‑regulated on myeloid  leukemias, head and neck squamous cell carcinomas, and several nonepithelial cancers (3, 5, 7). It is also up‑regulated on macrophages and monocytes at chronic inflammatory sites including rheumatoid arthritis synovium and glioblastoma (8‑10). FOLR2 knockout mice do not show gross morphological defects, but they exhibit increased sensitivity to arsenate-induced teratogenicity (11, 12).
