Re: In which type of tissue cells is CFTR located?

CFTR stands for Cystic Fibrosis Transmembrane Regulator protein.  It is a
transport protein responsible for the transport of chloride ions across the
apical membranes of epithelial cells in the lung, sweat glands, pancreas,
and other tissues.  Patients with cystic fibrosis have a defective CFTR
protein that cannot transport chloride ions.

Good luck with your assignment.
