Summary: This gene encodes a liver-specific member of the organic anion transporter family. The encoded protein is a transmembrane receptor that mediates the sodium-independent uptake of endogenous and xenobiotic compounds and plays a critical role in bile acid and bilirubin transport. Mutations in this gene are a cause of Rotor type hyperbilirubinemia. Alternative splicing of this gene and the use of alternative promoters results in transcript variants encoding different isoforms that differ in their tissue specificity.

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.

NM_001349920.2 → NP_001336849.1 solute carrier organic anion transporter family member 1B3 isoform 2

Status: REVIEWED

Description

Transcript Variant: This variant (2) represents use of an alternate promoter and therefore differs in the 5' UTR and 5' coding region, compared to variant 1. The promoter and 5' terminal exon sequence is from an endogenous retroviral LTR. (PMID: 22326869) The resulting isoform (2) is shorter and has a distinct N-terminus, compared to isoform 1. The protein encoded is primarily expressed in colon and pancreas cancers.
