Eukaryotic Transmembrane Transport

ATP-Binding Cassette Transporter (Wiki) 
"Eukaryotes do not possess any importers. ABC exporters or effluxers, which are both present in prokaryotes and eukaryotes, function as pumps that extrude toxins and drugs out of the cell.

In bacterial efflux systems, certain substances that need to be extruded from the cell include surface components of the bacterial cell (e.g. capsular polysaccharides, lipopolysaccharides, and teichoic acid), proteins involved in bacterial pathogenesis (e.g. hemolysis, heme-binding protein, and alkaline protease), heme, hydrolytic enzymes, S-layer proteins, competence factors, toxins, lantibiotics, bacteriocins, peptide antibiotics, drugs and siderophores.[9] They also play important roles in biosynthetic pathways, including extracellular polysaccharide biosynthesis[10] and cytochrome biogenesis."

Although most eukaryotic ABC transporters are effluxers, some are not directly involved in transporting substrates.

Since eukaryotic cells don't have ABC importers, I'm assuming that they rely on importers present in prokaryotes.  See
