Hydrоpаthy аnаlysis оf a membrane prоtein'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 small fragments but will not have access to transmembrane or cytosolic regions of proteins. You design a general experiment using trypsin and SDS-PAGE to address membrane protein association and orientation. Experiment: Treat one set of intact cells with trypsin and use a second set of untreated cells as a control source of the full-length protein. Use SDS-PAGE to separate the total cell proteins or proteins in an isolated plasma membrane fraction from both the treated and untreated cells. You find the following result: The protein from the trypsin treated sample is shorter (and therefore migrates further in the gel) than the sample from the untreated cells. With which of the following types of proteins are your results consistent?
