• Function: Transporter for the intake of folate. Uptake of folate in human placental choriocarcinoma cells occurs by a novel mechanism called potocytosis which functionally couples three components, namely the folate receptor, the folate transporter, and a V-type H(+)-pump.
• KEGG Pathway:
  Antifolate resistance (hsa01523)
  Vitamin digestion and absorption (hsa04977)
• Reactome Pathway: Metabolism of folate and pterines (R-HSA-196757)
