FOLR3 Gene

Name folate receptor 3 (gamma)
Description This gene encodes a member of the folate receptor (FOLR) family of proteins, which 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. Expression of this gene may be elevated in ovarian and primary peritoneal carcinoma. This gene is present in a gene cluster on chromosome 11. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n FOLR3, encoding the folate receptor‐gamma isoform, is emerging as a distinct member of the folate receptor family with potential roles in both disease diagnosis and folate physiology. Although its functions remain less characterized than those of FOLR1 (FRα) and FOLR2 (FRβ), several studies indicate that FOLR3 is coexpressed with FOLR1 in ovarian carcinoma effusions, with mRNA levels directly correlated between the two genes. This coexpression supports the use of folate receptor profiling as a tool to differentiate ovarian carcinoma from other malignancies and underlines the validity of targeting the folate receptor system in these tumors."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n \n "}, {"type": "p", "children": [{"type": "t", "text": "\n In addition, genetic association studies in neural tube defect populations have identified rare single nucleotide polymorphisms in FOLR3 that are significantly associated with myelomeningocele, suggesting that variability in this receptor may modulate folate uptake during embryogenesis and influence susceptibility to folate‐related developmental disorders."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "\n "}]}, {"type": "t", "text": "\n \n "}, {"type": "p", "children": [{"type": "t", "text": "\n Beyond its potential developmental importance, functional studies have begun to explore the role of FOLR3 in cellular folate metabolism.
