SLCO1B3, solute carrier organic anion transporter family member 1B3, is also known as solute carrier family 21 member 8 (SLC21A8). It is encoded by human SLCO1B3 gene and belongs to the SLC21A family of solute carriers. This gene is conserved in dog, Rhesus monkey, mouse, rat, and cow. It is documented that 55 organisms have orthologs with this gene. It’s restrictedly expressed in the liver and is involved in sodium-independent uptake of organic anions.
|Basic Information of SLCO1B3|
|Protein Name||Solute carrier organic anion transporter family member 1B3|
|Aliases||LST2, OATP1B3, OATP8, SLC21A8|
|Organism||Homo sapiens (Human)|
SLCO1B3 is a sodium-independent transmembrane transporter, which is involved in the sodium-independent uptake of numerous endogenous compounds, such as leukotriene C4, 17-beta-glucuronosyl estradiol and bilirubin. In addition, SLCO1B3 is also involved in the clearance of organic anions and bile acids from the liver. Also, it has been reported that SLCO1B3 polymorphisms are critical for optimizing the agent dose of voriconazole. Especially, cancer type SLCO1B3 mRNA can be potential serum-based colorectal cancer (CRC) biomarker. In addition, SLCO1B3 can be regarded as a biomarker for warfarin dose adjustment in Chinese populations. Moreover, SLCO1B3 activity can be inhibited by bortezomib in a substrate-dependent manner. In the clinic, SLCO1B3 has been found to be associated with prostate cancer progression and testicular cancer.
