Research Backgrounds

Function:

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.

PTMs:

The secreted form is derived from the membrane-bound form either by cleavage of the GPI anchor, or/and by proteolysis catalyzed by a metalloprotease.

Subcellular Location:

Cell membrane>Lipid-anchor. Secreted. Cytoplasmic vesicle. Cytoplasmic vesicle>Clathrin-coated vesicle. Endosome. Apical cell membrane.
Note: Endocytosed into cytoplasmic vesicles and then recycled to the cell membrane.

Tissue Specificity:

Primarily expressed in tissues of epithelial origin. Expression is increased in malignant tissues. Expressed in kidney, lung and cerebellum. Detected in placenta and thymus epithelium.

Family&Domains:

Belongs to the folate receptor family.
