Summary: Predicted to enable folic acid binding activity; folic acid receptor activity; and signaling receptor activity. Involved in circulatory system development; nervous system development; and regulation of signal transduction. Acts upstream of or within folic acid metabolic process. Predicted to be located in several cellular components, including apical plasma membrane; basolateral plasma membrane; and brush border membrane. Predicted to be active in external side of plasma membrane. Is expressed in several structures, including brain; early conceptus; genitourinary system; gut; and retina. Human ortholog(s) of this gene implicated in cerebral folate receptor alpha deficiency. Orthologous to human FOLR1 (folate receptor alpha). [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.
