英文摘要 | The cystic fibrosis transmembrane conductance regulator (CFTR) constitutes a linear conductance chloride channel, which is regulated by cAMP-dependent protein kinase phosphorylation at multiple sites located in the intracellular regulatory (R) domain, Studies in a lipid bilayer system, reported here, provide evidence for the control of CFTR chloride channel by its R domain, The exogenous R domain protein (encoded by exon 13 plus 85 base pairs of exon 14) interacted specifically with the CFTR molecule and inhibited the chloride conductance in a phosphorylation-dependent manner. Only the unphosphorylated R domain protein blocked the CFTR channel, Such functional interaction suggests that the putative gating particle of the CFTR chloride channel resides in the R domain. |
