Cystic Fibrosis: Role of Proteins in Gene Expression

Production of disfunctional membrane protein that controls chloride
ion movement across cell membranes of the cells of the respiratory passages
of the lungs and other organs of the body.
Chloride ions are trapped in the cells of the respiratory passages causing
thickening the mucus in the respiratory passages.
Relationship of the Structure of Proteins to their Functions.
Amino Acids
Primary Structure (Sequence of Amino Acids)
Secondary Structures(alpha helices or beta sheets)
Tertiary Structure (3-D Folding)
Quaternary Structure (Association of 2 or more polypeptide chains)
