OCTN2 plays a positive role in epididymal epithelial cells, and might be useful in the clinical treatment of male infertility by serving as a key regulatory factor.
Title: Carnitine/organic cation transporter 2 (OCTN2) contributes to rat epididymal epithelial cell growth and proliferation.
PKC activation resulted in an augmented Octn2 presence in cholesterol/sphingolipid-rich microdomains of plasma membrane (rafts) and increased co-precipitation of Octn2 with raft-proteins, caveolin-1 and flotillin-1.

Title: Inhibition of the OCTN2 carnitine transporter by HgCl2 and methylmercury in the proteoliposome experimental model: insights in the mechanism of toxicity.
The present study showed that muscle contraction facilitated carnitine uptake in skeletal muscles, possibly via the contraction-induced translocation of its specific transporter OCTN2 to the plasma membrane.
Title: Muscle contraction increases carnitine uptake via translocation of OCTN2.
Data suggests that Slc22a5 plays a role in kidney in reabsorption of carnitine from urine; with training in physical activity, expression of Slc22a5 mRNA is up-regulated in kidney.
Title: The effects of exercise training on γ-butyrobetaine hydroxylase and novel organic cation transporter-2 gene expression in the rat.
Lipopolysaccharide-induced inflammation generally downregulates glucose, fatty acid, and L-carnitine transporter expression; whether this leads to reductions in substrate availability to epithelial cells requires investigation.
Title: LPS-induced inflammation downregulates mammary gland glucose, fatty acid, and L-carnitine transporter expression at different lactation stages.
OCTN2 is functionally expressed in skeletal muscles and is involved in the import of carnitine for fatty acid oxidation, especially in highly oxidative muscles.
Title: OCTN2 is associated with carnitine transport capacity of rat skeletal muscles.
Present study demonstrates expression of octn2 and octn3 genes coding high affinity carnitine transporters, as well as presence of both proteins in neurons obtained from suckling and adult rats.
Title: High affinity carnitine transporters from OCTN family in neural cells.
This is the first report showing a functional apical OCTN2 in the renal medulla and a functional apical OCTN3 in both renal cortex and medulla.

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.
