folate receptor
英[ˈfəuleit rɪˈseptə]美[ˈfoˌlet rɪˈseptər]
Folate receptors bind folate and reduced folic acid derivatives and mediates delivery of tetrahydrofolate to the interior of cells. It is then converted from monoglutamate to polyglutamate forms - such as 5- methyltetrahydrofolate - as only monoglutamate forms can be transported across cell membranes.
