Enables bile acid transmembrane transporter activity and organic anion transmembrane transporter activity. Involved in several processes, including bile acid signaling pathway; organic anion transport; and response to 17alpha-ethynylestradiol. Located in basal plasma membrane. Biomarker of Dubin-Johnson syndrome; cholestasis; and fatty liver disease. Orthologous to human SLCO1A2 (solute carrier organic anion transporter family member 1A2).
