You are studying a protein that normally resides in the plasma membrane. The organization of this protein is depicted in the figure below, where the gray boxes labeled A, B, and C represent transmembrane regions and the segments labeled 1, 2, 3, and 4 represent the portions of the protein between the transmembrane regions. You also know that segments 2 and 4 contain N-linked oligosaccharides. Draw the topology of the protein as it is inserted in the plasma membrane and explain your choice. Be sure to label the cytoplasmic and extracellular face of your membrane and the N-terminus and C-terminus of your protein.
