Solute carrier organic anion transporter family member 1B3 (SLCO1B3) also known as organic anion-transporting polypeptide 1B3 (OATP1B3) is a protein that in humans is encoded by the SLCO1B3 gene. [5]
OATP1B3 is a 12-transmembrane domain influx transporter. Normally expressed in the liver, the transporter functions to uptake large, non-polar drugs and hormones from the portal vein.
OATP1B3 has also been identified as a transporter aberrantly expressed in prostate cancer and implicated in prostate cancer progression. [6] Increasing mRNA expression of OATP1B3 was also correlated to prostate cancer Gleason score. [7]
In addition, lower expression of OATP1B3 mRNA was also detected in testicular cancer. [7]
Small molecules that are transported by SLCO1B3 include: [8]
Bosentan, sold under the brand name Tracleer among others, is a dual endothelin receptor antagonist medication used in the treatment of pulmonary artery hypertension (PAH).
Rotor syndrome is a rare cause of mixed direct (conjugated) and indirect (unconjugated) hyperbilirubinemia, relatively benign, autosomal recessive bilirubin disorder characterized by non-hemolytic jaundice due to the chronic elevation of predominantly conjugated bilirubin.
HNF1 homeobox A, also known as HNF1A, is a human gene on chromosome 12. It is ubiquitously expressed in many tissues and cell types. The protein encoded by this gene is a transcription factor that is highly expressed in the liver and is involved in the regulation of the expression of several liver-specific genes. Mutations in the HNF1A gene have been known to cause diabetes. The HNF1A gene also contains a SNP associated with increased risk of coronary artery disease.
Multidrug resistance-associated protein 2 (MRP2) also called canalicular multispecific organic anion transporter 1 (cMOAT) or ATP-binding cassette sub-family C member 2 (ABCC2) is a protein that in humans is encoded by the ABCC2 gene.
Solute carrier organic anion transporter family member 1B1 is a protein that in humans is encoded by the SLCO1B1 gene. Pharmacogenomic research indicates that genetic variations in this gene are associated with response to simvastatin. Clinical guidelines exist that can guide dosing of simvastatin based on SLCO1B1 gene variant using genotyping or whole exome sequencing.
Solute carrier family 22 member 11 is a protein that in humans is encoded by the SLC22A11 gene.
Solute carrier family 22 member 8, or organic anion transporter 3 (OAT3), is a protein that in humans is encoded by the SLC22A8 gene.
Solute carrier organic anion transporter family member 1A2 is a protein that in humans is encoded by the SLCO1A2 gene.
Solute carrier organic anion transporter family member 2B1 also known as organic anion-transporting polypeptide 2B1 (OATP2B1) is a protein that in humans is encoded by the gene SLCO2B1.
Organic solute transporter alpha, also known as OST-alpha, is a protein which in humans is encoded by the SLC51A gene.
Solute carrier organic anion transporter family member 4A1 is a protein that in humans is encoded by the SLCO4A1 gene.
Solute carrier family 22 member 7 is a protein that in humans is encoded by the gene SLC22A7.
Solute carrier family 22 member 9 is a protein that in humans is encoded by the SLC22A9 gene.
Solute carrier organic anion transporter family member 3A1 is a protein that in humans is encoded by the SLCO3A1 gene.
The organic anion transporter 1 (OAT1) also known as solute carrier family 22 member 6 (SLC22A6) is a protein that in humans is encoded by the SLC22A6 gene. It is a member of the organic anion transporter (OAT) family of proteins. OAT1 is a transmembrane protein that is expressed in the brain, the placenta, the eyes, smooth muscles, and the basolateral membrane of proximal tubular cells of the kidneys. It plays a central role in renal organic anion transport. Along with OAT3, OAT1 mediates the uptake of a wide range of relatively small and hydrophilic organic anions from plasma into the cytoplasm of the proximal tubular cells of the kidneys. From there, these substrates are transported into the lumen of the nephrons of the kidneys for excretion. OAT1 homologs have been identified in rats, mice, rabbits, pigs, flounders, and nematodes.
This family of proteins are found both in prokaryotes and eukaryotes. In mammals, they are transmembrane proteins with functions in the liver and in the intestine. They are members of the solute carrier family of cotransporter genes which include SLC10A1 and SLC10A2.
Eluxadoline, sold under the brand names Viberzi and Truberzi, is a medication taken by mouth for the treatment of diarrhea and abdominal pain in individuals with diarrhea-predominant irritable bowel syndrome (IBS-D). It was approved for use in the United States in 2015. The drug originated from Janssen Pharmaceutica and was developed by Actavis.
Members of the organic solute transporter (OST) family have been characterized from a small bottom feeding species of fish called the little skate, Raja erinacea. Members have also been characterized from humans and mice. The OST family is a member of the larger group of secondary carriers, the APC superfamily.
Solute carrier organic anion transporter family member 4C1 is a protein that in humans is encoded by the SLCO4C1 gene, which is located on chromosome 5q21. The OATP4C1 protein is expressed in the basolateral membrane of the nephron of the human kidney, where it is involved in the uptake of organic anions for elimination in the urine. The drug digoxin is an important substrate of this transporter.
Members of the Organo Anion Transporter (OAT) Family are membrane transport proteins or 'transporters' that mediate the transport of mainly organic anions across the cell membrane. Therefore, OATPs are present in the lipid bilayer of the cell membrane, acting as the cell's gatekeepers. OATPs belong to the Solute Carrier Family (SLC) and the major facilitator superfamily.
