Summary: Enables folic acid transmembrane transporter activity and methotrexate transmembrane transporter activity. Involved in folate import across plasma membrane and methotrexate transport. Located in apical plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in several diseases, including abdominal aortic aneurysm; cleft lip; dextro-looped transposition of the great arteries; hematologic cancer; and malaria. Orthologous to human SLC19A1 (solute carrier family 19 member 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
