Gene type: protein coding
RefSeq status: REVIEWED
Organism: Mus musculus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus

Summary: This gene encodes a receptor protein located on the plasma membrane that mediates folate uptake by cells. Mice lacking the product of this gene show no defects in embryonic development and grow normally into fertile adults. However, such mice were found to be highly susceptible to the teratogenic effects of arsenic. Alternate splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2014]

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.
