Structure of the transporter protein Asc1/CD98hc with its two components: CD98hc (fuchsia) and Asc1 (multicolor), which extend from the inside of the cell (cytoplasm) to the outside, crossing its membrane.
Photo: electron microscopy image, showing the CD98hc component protruding from the membrane, and corresponding transverse bands of the Asc1 protein.
