What is the function of CFTR protein?
The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.
What is the effect on the CF protein and why?
Mutations in the CFTR gene cause the CFTR protein to malfunction or not be made at all, leading to a buildup of thick mucus, which in turn leads to persistent lung infections, destruction of the pancreas, and complications in other organs. Cystic fibrosis is an example of a recessive disease.
What happens to CFTR protein?
The cystic fibrosis transmembrane conductance regulator (CFTR) protein helps to maintain the balance of salt and water on many surfaces in the body, such as the surface of the lung. When the protein is not working correctly, chloride — a component of salt — becomes trapped in cells.
What is the CFTR protein What is its structure?
The CFTR protein is composed of 1,480 amino acids—the building blocks of all proteins—and is located on the surface of many cells in the body. The CFTR protein contains a single chain of amino acids that are grouped in five functional regions called domains.
Why does CF cause salty sweat?
Why do people with CF have salty skin? In people with CF there is a problem in the transport of chloride across cell membranes. This causes thicker, stickier mucus in the lungs and digestive system, but also results in higher levels of chloride (as salt) in sweat compared with those who do not have cystic fibrosis.
Why is CF sweat salty?
As CF is caused by a faulty gene that controls the movement of chloride and water into and out of cells, people with CF often sweat more than people without the condition, and this sweat contains high levels of chloride, which can crystallise into salt visibly on the skin.
How does CF affect the respiratory system?
The abnormal electrolyte transport system in CF causes the cells in the respiratory system, especially the lungs, to absorb too much sodium and water. This causes the normal thin secretions in the lungs to become very thick and hard to move. These thick secretions increase the risk for frequent respiratory infections.
Does CF affect the skin?
Why do CF patients have greasy stools?
About 90 percent of people with CF have sticky mucus that blocks ducts in the pancreas and prevents enzymes from reaching the small intestine to digest food. Undigested food in the intestines can cause pain, cramping, gas and either loose, greasy, floating stools or constipation and blockages.
What organs are affected by CF?
CF causes thick mucus that clogs certain organs, such as the lungs, pancreas, and intestines. This may cause malnutrition, poor growth, frequent respiratory infections, breathing problems, and chronic lung disease.
What does CF stand for in protein category?
CF stands for Carrier-Free. We add 50 µg BSA (carrier protein) per 1 µg of protein for stability. The carrier-free version does not contain BSA. Usually proteins with BSA can be stored at a more dilute concentration than their carrier-free counterparts and may have a longer shelf-life.
What happens to the CFTR protein in cystic fibrosis?
Normally, the CFTR protein controls the movement of ions from inside the cell to outside the cell. In people who have cystic fibrosis, the mutated gene causes the protein to not work properly, which, in turn, affects the movement of sodium and water.
Genes are inherited in pairs, with one gene inherited from each parent to make the pair. Cystic fibrosis occurs when both genes in the pair have a mutation. A person with cystic fibrosis inherits one CF gene from each parent. Cystic fibrosis is a genetic disorder caused by inheriting a pair of genes that are mutated or not working properly.
What happens to your body when you have cystic fibrosis?
Cystic fibrosis (CF) is a genetic condition that affects a protein in the body. People who have cystic fibrosis have a faulty protein that affects the body’s cells, tissues, and the glands that make mucus and sweat.
