Is Cystic Fibrosis Transmembrane Conductance Regulator an integral or peripheral plasma membrane protein?
Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is an integral plasma membrane protein. It functions as a chloride channel, playing a crucial role in regulating ion transport across epithelial cell membranes. CFTR spans the lipid bilayer, which is characteristic of integral membrane proteins, as it is embedded within and interacts with the hydrophobic core of the membrane.
What else can I help you with?
Is cystic fibrosis a mutation?
yes, it is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). The most common mutation, which results in a loss of the amino acid phenylalanine
Which gene causes cystic fibrosis?
Cystic Fibrosis is caused by the gene which codes for the protein CFTR--Cystic Fibrosis Transmembrane Conductance Regulator, which is found on chromosome 7. The protein transports chloride ions across epithelial cell membranes.
What does CFTR-ΔF508 refer to?
CFTR-ΔF508 refers to a specific mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene where phenylalanine (F) at position 508 is deleted (Δ). This mutation leads to the production of a faulty CFTR protein, resulting in impaired chloride ion transport across cell membranes and causing the symptoms of cystic fibrosis.
How many exons are in CFTR?
The CFTR (cystic fibrosis transmembrane conductance regulator) gene contains 27 exons. These exons encode the protein responsible for regulating chloride ions across epithelial cell membranes, and mutations in this gene are associated with cystic fibrosis.
What is the sequence of amino acid in cystic fibrosis?
The sequence of amino acids in cystic fibrosis is caused by a mutation in the CFTR gene, which leads to the production of a faulty cystic fibrosis transmembrane conductance regulator protein. This mutated protein results in abnormal function, leading to the characteristic symptoms of cystic fibrosis such as thick mucus production.
What does a CFTR gene stand for?
CFTR gene stands for Cystic Fibrosis Transmembrane Conductance Regulator gene. It is responsible for encoding a protein that regulates the flow of ions across cell membranes, particularly in the lungs and digestive system. Mutations in this gene can lead to cystic fibrosis, a genetic disorder affecting the lungs and digestive system.
What cells are affected by cystic fibrosis?
The protein affected by cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator or CFTR. CFTR acts as a channel that transports negatively charged chloride ions into and out of cells. This helps control the flow of water in tissues. CFTR also regulates the function of other channels that transport positive sodium ions into and out of cells.
What role does cftr play in the body?
The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane regulator.
What kind of pattern of inheritance of cystic fibrosis?
Inheritance - Autosomal recessive, requires mutations on both alleles - A single gene on chromosome 7, which encodes for the cystic fibrosis transmembrane conductance regulator - There are over 1000 different mutations for this gene - The most common is Delta F508, which makes up 67% of all mutations in the Caucasian population - Caucasians most effected
What does cf-tr stands for?
"CF-TR" typically stands for "Cystic Fibrosis Transmembrane Conductance Regulator." It refers to a protein that functions as a channel for chloride ions across cell membranes and is crucial for maintaining the balance of salt and water in various tissues. Mutations in the CFTR gene are responsible for cystic fibrosis, a genetic disorder that affects the respiratory and digestive systems.
What is the effect of CFTR on tissue function?
CFTR (cystic fibrosis transmembrane conductance regulator) is a protein that regulates chloride and bicarbonate transport across cell membranes. Mutations in the CFTR gene can lead to dysfunction in various tissues, particularly affecting the lungs and digestive system in cystic fibrosis patients. This results in thick, sticky mucus production, impaired ciliary function, and increased susceptibility to infections.
What is cause slide of cystic fibrosis?
Cystic fibrosis (CF) is caused by mutations in the CFTR gene, which encodes the cystic fibrosis transmembrane conductance regulator protein. This protein is responsible for regulating the movement of chloride ions across epithelial cell membranes. Mutations lead to dysfunctional or absent CFTR protein, resulting in thick, sticky mucus buildup in various organs, particularly the lungs and pancreas. This can cause respiratory infections, digestive issues, and other complications characteristic of CF.
