The CFTR protein is a particular type of protein called an ion channel. The abnormal mucus obstructs the airways and glands, leading to the characteristic signs and symptoms of cystic fibrosis. Group of answer choices primary structure tertiary structure secondary structure Yamazaki J, Britton F, Collier ML, Horowitz B, Hume JR. Biophys J. 2020 Elsevier Masson SAS. All rights reserved. What Happens? The CFTR protein reaches the cell surface butchloridetransportthrough the channel is defective. More than 2,000 variants, distributed throughout the CFTR gene, have been identified, with different effects on the gene and protein expression and function. Epithelial cells are composed of two membranes with distinct functions depending on the tissue and on their ion channels, exchangers, cotransporters, or pumps. 8600 Rockville Pike Loffing J, Moyer BD, McCoy D, Stanton BA.
