Phosphatidylcholines 29-31 ATP binding cassette subfamily B member 4 Homo sapiens 4-9 23468132-6 2013 The ABCB4-mediated efflux of PC, PE, and SM was significantly stimulated by taurocholate, while the efflux of PE and SM was much less than that of PC. Phosphatidylcholines 147-149 ATP binding cassette subfamily B member 4 Homo sapiens 4-9 23305784-1 2013 Although human MDR1 and MDR3 share 86% similarity in their amino acid sequences and are predicted to share conserved domains for drug recognition, their physiological transport substrates are quite different: MDR1 transports xenobiotics and confers multidrug resistance, while MDR3 exports phosphatidylcholine into bile. Phosphatidylcholines 290-309 ATP binding cassette subfamily B member 4 Homo sapiens 24-28 23305784-1 2013 Although human MDR1 and MDR3 share 86% similarity in their amino acid sequences and are predicted to share conserved domains for drug recognition, their physiological transport substrates are quite different: MDR1 transports xenobiotics and confers multidrug resistance, while MDR3 exports phosphatidylcholine into bile. Phosphatidylcholines 290-309 ATP binding cassette subfamily B member 4 Homo sapiens 277-281 23141892-2 2012 It is caused by a mutation of the gene ABCB4, which encodes the canalicular protein ABCB4/MDR3, a flippase that plays an essential role in the secretion of phosphatidylcholine into bile. Phosphatidylcholines 156-175 ATP binding cassette subfamily B member 4 Homo sapiens 84-89 23141892-2 2012 It is caused by a mutation of the gene ABCB4, which encodes the canalicular protein ABCB4/MDR3, a flippase that plays an essential role in the secretion of phosphatidylcholine into bile. Phosphatidylcholines 156-175 ATP binding cassette subfamily B member 4 Homo sapiens 90-94 22859919-4 2012 There are two mechanisms to protect the canalicular membrane from solubilization by bile salts; ABCB4 secretes phosphatidylcholine into bile to form mixed micelles with bile salts, and ATP8B1 maintains the canalicular membrane in a liquid-ordered state.
