Folate deficiency alters the expression of folate transporters RFC and folate exporter ABCG2 in the adult group differently than weanling group and young group both at the transcriptional and translational level, which in turn was found to be epigenetically regulated by promoter methylation of the RFC and ABCG2 genes.

decreased levels of PCFT and RFC expression in rat PPM are due to decreased association of these proteins with lipid rafts (LR) at the PPM

Data suggest that malabsorption of folate in colon associated with alcoholism is due, in part, to down-regulation of folate transporter expression and association with lipid rafts (for both RFC/Slc19a1 and proton-coupled folate transporter/Slc46a1).
Title: Folate malabsorption is associated with down-regulation of folate transporter expression and function at colon basolateral membrane in rats.
Downregulation in the expression of the PCFT and the RFC in colon results in reduced levels of these transporters in colon apical membrane lipid rafts as a mechanism of folate malabsorption during chronic alcoholism.
Title: Reduced levels of folate transporters (PCFT and RFC) in membrane lipid rafts result in colonic folate malabsorption in chronic alcoholism.

Three minor mRNA forms resulted from absent splicing of intron III, a shortened exon III, and a shortened exon IV. The minor transcripts were predicted to result in translation products with 7 or 6 instead of 12 transmembrane domains.

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.
