Cystic Fibrosis Transmembrane Regulator (CFTR), the gene responsible for cystic fibrosis.

see cystic fibrosis transmembrane conductance regulator.

CFTR (cystic fibrosis transmembrane conductance regulator, ATP-binding cassette (sub-family C, member 7)) is a human gene that provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the cell membrane. Such channels are found in tissues that produce mucus, sweat, saliva, tears and digestive enzymes.
