摘要: Abstract The recent identification of the cystic fibrosis (CF) gene and its putative protein product, CF transmembrane conductance regulator (CFTR), enabled us to synthesize oligopeptides corresponding with a predicted extracellular domain (position 103–117; peptide A) cytoplasmic 501–515; B) constituting phenylalanine deletion (F 508) observed in majority mutations. Immunobiochemical studies antibodies directed against these peptides revealed presence two CFTR candidate proteins (155 195 kDa) various types epithelial cells. Immunolocalization performed on slices human duodenum showed strongest expression endoplasmic reticulum (RER) mucusproducing Goblet Labeling is also demonstrated RER apical membranes villus crypt cells, however, weaker extent.
