Folate transporter. Highly expressed in pharynx and posterior part of the intestine. Expressed at lower levels in the body wall muscles, head muscles, and vulva muscles. Highly expressed in the intestine of the early larva, levels decrease in the later stages of development. Worms display defects in folate uptake, reproduction and movement. Belongs to the reduced folate carrier (RFC) transporter (TC 2.A.48) family.
