Hepatic OSTalpha-OSTbeta expression is induced by hypoxia.
Title: The organic solute transporters alpha and beta are induced by hypoxia in human hepatocytes.
Ostbeta is required for both proper trafficking of Ostalpha and formation of the functional transport unit, and identify specific residues of Ostbeta critical for these processes.
Title: β-Subunit of the Ostα-Ostβ organic solute transporter is required not only for heterodimerization and trafficking but also for function.
The present report summarizes the evidence for a pleiotropic role of Ostalpha-Ostbeta in different tissues.
Title: Pleiotropic functions of the organic solute transporter Ostα-Ostβ.
human OSTalpha is a glycoprotein that requires interaction with OSTbeta to reach the plasma membrane. However, glycosylation of OSTalpha is not necessary for interaction with the beta subunit or for membrane localization .
Title: N-Glycosylation of the alpha subunit does not influence trafficking or functional activity of the human organic solute transporter alpha/beta.
The mRNA expression of OSTalpha-OSTbeta was significantly reduced (OSTalpha: 3.3-fold, P = 0.006; OSTbeta: 2.6-fold, P = 0.03) in normal-weight but not overweight gallstone carriers

Demonstrate association of OST-alpha and OST-beta to determine trafficking to plasma membrane and activity.
Title: Protein-protein interactions and membrane localization of the human organic solute transporter.
These results indicate that expression of Ostalpha and Ostbeta are highly regulated in response to cholestasis and that this response is dependent on the FXR bile acid receptor.
Title: Upregulation of a basolateral FXR-dependent bile acid efflux transporter OSTalpha-OSTbeta in cholestasis in humans and rodents.
OSTalpha/OSTbeta expression is induced by bile acids through ligand-dependent transactivation of both OST genes by the nuclear bile acid receptor/farnesoid X receptor (FXR).
Title: The nuclear receptor for bile acids, FXR, transactivates human organic solute transporter-alpha and -beta genes.

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.
