1 UNLABELLED: The ABCB4 transporter mediates phosphatidylcholine (PC) secretion at the canalicular membrane of hepatocytes and its genetic defects cause biliary diseases. Phosphatidylcholines ATP binding cassette subfamily B member 4 Homo sapiens
2 UNLABELLED: The ABCB4 transporter mediates phosphatidylcholine (PC) secretion at the canalicular membrane of hepatocytes and its genetic defects cause biliary diseases. Phosphatidylcholines ATP binding cassette subfamily B member 4 Homo sapiens
3 ABCB4-mediated PC secretion was also increased by pharmacological activation of protein kinases A or C and decreased by inhibition of these kinases. Phosphatidylcholines ATP binding cassette subfamily B member 4 Homo sapiens
4 CONCLUSION: We identified disease-associated variants of ABCB4 involved in the phosphorylation of its N-terminal domain and leading to decreased PC secretion. Phosphatidylcholines ATP binding cassette subfamily B member 4 Homo sapiens
