What is the official name of the SLCO1B1 gene?
The official name of this gene is “solute carrier organic anion transporter family, member 1B1.”
SLCO1B1 is the gene's official symbol. The SLCO1B1 gene is also known by other names, listed below.

What is the normal function of the SLCO1B1 gene?
The SLCO1B1 gene provides instructions for making a protein called organic anion transporting polypeptide 1B1, or OATP1B1. This protein is found in liver cells; it transports compounds from the blood into the liver so that they can be cleared from the body. For example, the OATP1B1 protein transports bilirubin, which is a yellowish substance that is produced when red blood cells are broken down. In the liver, bilirubin is dissolved in a digestive fluid called bile and then excreted from the body. The OATP1B1 protein also transports certain hormones, toxins, and drugs into the liver for removal from the body. Drugs transported by the OATP1B1 protein include statins, which are used to treat high cholesterol; heart disease medications; certain antibiotics; and some drugs used for the treatment of cancer.
Does the SLCO1B1 gene share characteristics with other genes?
The SLCO1B1 gene belongs to a family of genes called SLC (solute carriers).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
