Question

Quizplus · Accepted Answer

CFTR (cystic fibrosis transmembrane conductance regulator) functions by forming a chloride ion channel in the membrane. This channel regulates the movement of chloride ions across cell membranes, which is important for proper hydration of certain tissues (such as the lungs and pancreas). Mutations in the CFTR gene can lead to the development of cystic fibrosis.
