Regulation of multidrug resistance‐associated protein 2 by calcium signaling in mouse liver
Laura N. Cruz, Mateus T. Guerra, Emma Kruglov, Albert Mennone, Celia R. S. Garcia, Ju Chen, Michael H. Nathanson – 23 June 2010 – Multidrug resistance associated protein 2 (Mrp2) is a canalicular transporter responsible for organic anion secretion into bile. Mrp2 activity is regulated by insertion into the plasma membrane; however, the factors that control this are not understood. Calcium (Ca2+) signaling regulates exocytosis of vesicles in most cell types, and the type II inositol 1,4,5‐triphosphate receptor (InsP3R2) regulates Ca2+ release in the canalicular region of hepatocytes.
