Predicted to enable several functions, including ABC-type transporter activity; glutathione transmembrane transporter activity; and prostaglandin transmembrane transporter activity. Involved in several processes, including bile acid signaling pathway; positive regulation of smooth muscle cell proliferation; and response to xenobiotic stimulus. Located in basolateral plasma membrane and external side of apical plasma membrane. Biomarker of cholestasis and extrahepatic cholestasis. Orthologous to human ABCC4 (ATP binding cassette subfamily C member 4). [provided by Alliance of Genome Resources, Apr 2022]
