Hydropathy analysis of a membrane protein's amino acid sequence predicts the protein's transmembrane segments and orientation in the membrane. It is necessary to confirm those predictions with experimental analysis. One experimental approach for plasma membrane proteins is to use the protease trypsin to digest extracellular domains of these proteins. (Trypsin is hydrophilic and cannot cross the plasma membrane to enter the cell.) When added to cells, trypsin digests the hydrophilic portions of plasma membrane proteins exposed outside the cell into...
