investigation of role of OATP1B3 in drug metabolism/distribution: Data indicate that hepatic uptake of telmisartan mainly consists of a saturable process mediated by OATP1B3.
Title: The involvement of organic anion transporting polypeptide in the hepatic uptake of telmisartan in rats: PET studies with [¹¹C]telmisartan.
Oatp2 and Oatp4 levels were unaffected during obstructive cholestasis.
Title: Extrahepatic cholestasis downregulates Oatp1 by TNF-alpha signalling without affecting Oatp2 and Oatp4 expression and sodium-independent bile salt uptake in rat liver.
Detailed DNA sequence analysis reveales major functional features of the sequence.
Title: Determination of transcription start site and analysis of promoter sequence, splice junction sites, intron sequence and codon usage bias of rat liver-specific organic anion transporter-1 (rlst-1/Oatp-4/Slc21a10) gene.

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.

mRNA and Protein(s)

NM_001270586.1 → NP_001257515.1 solute carrier organic anion transporter family member 1B2 isoform 2

See identical proteins and their annotated locations for NP_001257515.1

Status: VALIDATED

Description

Transcript Variant: This variant (2, also known as rlst-1b) uses an alternate in-frame splice junction at the 3' end of an exon compared to variant 1. The resulting isoform (2) has the same N- and C-termini but is shorter compared to isoform 1.
