4. CFTR is a protein in the plasma membrane of epithelial cells. Plasma membrane proteins follow a similar pathway to secreted protein, but they remain in the membrane at each step in the pathway. • Draw an “X” or star to show where CFTR will be synthesized. • Then indicate the compartments through which the CFTR protein will pass to get to the plasma membrane, using arrows to show the movement of CFTR through these compartments.
