Mouse Anti-FOLR1 (Folate Receptor alpha, FR-alpha, Adult Folate-binding Protein, FBP, Folate Receptor 1, Folate Receptor, Adult, KB cells FBP, Ovarian Tumor-associated Antigen MOv18, FOLR) (APC)
Folate receptor 1 (FOLR1; also folate receptor alpha, folate binding protein 1, and MOv18) is a 37-42kD member of the folate receptor family. FOLR1 is expressed in reticulocytes and placenta, plus renal, mammary, and thymic epithelium, where it mediates the transport of 5-methyltetrahydrofolate into the cell. The human FOLR1 preproprecursor is 257aa in length. It codes for a GPI-linked glycoprotein that is 210aa in size (aa25-234). There are two forms of FOLR1. One is GPI-linked, while the other is a soluble MMP cleavage product (aa25-226). There is one potential alternate splice form that shows a five aa substitution for aa121-205. Over aa25-233, human FOLR1 shares 83% aa identity with mouse FOLR1.
