Why is it important that proteins get targeted to the right cellular location? (11) correct answers Each protein has a specific function at its intended destination in the cell and failing to complete that task can result in the cell not functioning properly. Ex. in cystic fibrosis the CFTR protein is not able to reach the membrane leading to fluid buildup in the lungs. How do proteins get to the appropriate targets within the cell? (11) correct answers Specific sequences of amino acids can s...
