SLCO1B1

(redirected from OATP1B1)

SLCO1B1

A gene on chromosome 12p12 that encodes a transporter which mediates Na+-independent uptake of organic anions—e.g., pravastatin, taurocholate, methotrexate, dehydroepiandrosterone sulfate, 17-beta-glucuronosyl oestradiol, oestrone sulfate, prostaglandin E2, thromboxane B2, leukotriene C3, leukotriene E4, thyroxine and triiodothyronine. SLCO1B1 may play a key role in clearing bile acids and organic anions from the liver.

Molecular pathology
Defects in SLCO1B1 are a cause of Rotor syndrome.

The rs4149056 polymorphism causes the perturbation of the OATP1B1 localization in the cell membrane of hepatocytes reducing its transport activity, which consequently results in increased plasma concentration and systemic exposure of simvastatin, thus leading to the increased risk of muscle toxicity [13].

Because of the structure and size of MCs, active uptake into cells occurs via organic anion-transporting polypeptides (OATP/Oatp), as confirmed for liver-specific human OATP1B1 and OATP1B3, mouse Oatp1b2 (mOatp 1b2), skate Oatp 1d1, and the more widely distributed OATP1A2 expressed, for example, at the blood--brain barrier.
