Foliate receptor 3 (FOLR3), also known as folate receptor gamma or placental-specific folate receptor, is a member of the folate receptor family that mediates cellular uptake of folate and its derivatives via high-affinity binding. Encoded by the FOLR3 gene, this glycosylphosphatidylinositol (GPI)-anchored protein is primarily expressed in hematopoietic cells and placental trophoblasts. Unlike FOLR1 and FOLR2. which are linked to epithelial cancers and macrophage-related pathologies, FOLR3 shows restricted tissue expression, suggesting specialized roles in folate transport during erythropoiesis and placental development.
Recombinant human FOLR3 protein is typically produced in eukaryotic systems (e.g., CHO cells) to ensure proper post-translational modifications, including glycosylation, which is critical for ligand-binding activity. Its soluble form, engineered by removing the GPI anchor, facilitates in vitro studies by mimicking extracellular domain functionality. Research focuses on its interaction with folate analogs, receptor trafficking mechanisms, and potential as a biomarker in hematologic disorders like acute myeloid leukemia, where overexpression has been observed.
Additionally, recombinant FOLR3 serves as a tool for developing folate-conjugated therapeutic agents, leveraging receptor-mediated endocytosis for targeted drug delivery. Its unique expression profile and structural properties make it valuable for exploring tissue-specific folate metabolism and designing precision therapies for conditions involving dysregulated folate uptake.
