HEK293T Human FOLR1 Stable Cell Line

Folate receptor alpha (FOLR1) is a ~29 kDa protein. Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. Has high affinity for folate and folic acid analogs at neutral pH. Exposure to slightly acidic pH after receptor endocytosis triggers a conformation change that strongly reduces its affinity for folates and mediates their release. Required for normal embryonic development and normal cell proliferation. FOLR1 is the therapeutic target of mirvetuximab soravtansine (Elahere).
