A protein that is normally not expressed in epithelial cells has been induced in these cells and has been engineered such that a GPI anchor is attached to it as it is processed in the ER. Would you expect to find this protein in the apical (A) or basolateral (B) domain of the plasma membrane in these cells? Write down A or B as your answer.
