title: Membrane protein oligomeric structure and transport function.
abstract: Proteins which traverse membranes tend to have a dimeric structure in which the dimer is arranged asymmetrically across the membrane with the axis of symmetry perpendicular to the membrane plane. This general structure is well suited to the function of transporting nutrients across the cell membrane.
