"Regulation of epithelial chloride flux, which is defective in patients with cystic fibrosis, may be mediated by phosphorylation of the cystic fibrosis transmembrane conductance regulator (CFTR) by cyclic AMP-dependent protein kinase (PKA) or protein kinase C (PKC). CFTR regulates both HCO(3)(-) secretion and HCO(3)(-) salvage in secretory epithelia."^^ . "Edited: Gopinathrao, G, 2008-11-24 14:15:13"^^ . . . . . . . .
