Anti-CFTR Antibody, a.a. 1370-1380, clone M3A7

170 kDa

CFTR (Cystic Fibrosis Transmembrane Regulator) is an integral membrane protein shown to be involved in the transport of chloride ions. It is found on the surface of the epithelial cells lining the lungs and other organs. CFTR defects are the cause of cystic fibrosis.

Cystic Fibrosis (CF) is a common lethal genetic disease caused by mutations of the gene coding for the cystic fibrosis transmembrane conductance factor, a cAMP regulated chloride channel. Approximately 70% of all CF cases share the deletion of a phenylalanine at position 508 (delta F508) which results in abnormal chloride transport. Since the CF mutation is lethal, most often by lung and liver disease, it raises the question of why this genetic disease remains as common as it is. One possible explanation is that Salmonella typhi has been shown to use CFTR to enter intestinal epithelial cells and that delta F508 heterozygote and homozygote mice showed 86% and 100% reductions in S.typhi intestinal submucosal uptake.
