Abnormal localization of cystic fibrosis transmembrane conductance regulator in primary cultures of cystic fibrosis airway epithelia.

Abstract excerpt

Cystic fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR), a membrane glycoprotein that forms Cl- channels. Previous work has shown that when some CF-associated mutants of CFTR are expressed in heterologous cells, their glycosylation is incomplete. That observation led to the hypothesis that such mutants are not delivered to the plasma membrane where they can...
