Subcellular localization of bile acid, cholesterol, aminophospholipid, and copper transporters in various species
For each transporter, the apical or basolateral localization in a particular tissue and/or species is provided. Species included rat (R), mouse (M), human (H), and bovine (B). Detailed information regarding particular cellular populations or regions of the tissue are provided for some transporter isoforms. N.D., not determined.
