Phosphorylation-dependent 14-3-3 protein interactions regulate CFTR biogenesis
Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP/protein kinase A (PKA)-regulated chloride channel whose phosphorylation controls anion secretion across epithelial cell apical membranes. We examined the hypothesis that cAMP/PKA stimulation regulates CFTR biogenesis posttranslationally, based on predicted 14-3-3 binding motifs within CFTR and forskolin-induced CFTR expression...
متن کاملPromotion of importin α–mediated nuclear import by the phosphorylation-dependent binding of cargo protein to 14-3-3
14-3-3 proteins are phosphoserine/threonine-binding proteins that play important roles in many regulatory processes, including intracellular protein targeting. 14-3-3 proteins can anchor target proteins in the cytoplasm and in the nucleus or can mediate their nuclear export. So far, no role for 14-3-3 in mediating nuclear import has been described. There is also mounting evidence that nuclear i...
متن کاملStructural modulation of phosducin by phosphorylation and 14-3-3 protein binding.
Phosducin (Pdc), a highly conserved phosphoprotein, plays an important role in the regulation of G protein signaling, transcriptional control, and modulation of blood pressure. Pdc is negatively regulated by phosphorylation followed by binding to the 14-3-3 protein, whose role is still unclear. To gain insight into the role of 14-3-3 in the regulation of Pdc function, we studied structural chan...
متن کاملMultisite phosphorylation of 14-3-3 proteins by calcium-dependent protein kinases.
Plant 14-3-3 proteins are phosphorylated at multiple sites in vivo; however, the protein kinase(s) responsible are unknown. Of the 34 CPK (calcium-dependent protein kinase) paralogues in Arabidopsis thaliana, three (CPK1, CPK24 and CPK28) contain a canonical 14-3-3-binding motif. These three, in addition to CPK3, CPK6 and CPK8, were tested for activity against recombinant 14-3-3 proteins χ and ...
متن کاملPhosphorylation-Dependent Binding of 14-3-3 to the Polarity Protein Par3 Regulates Cell Polarity in Mammalian Epithelia
The mammalian homologs of the C. elegans partitioning-defective (Par) proteins have been demonstrated to be necessary for establishment of cell polarity. In mammalian epithelia, the Par3/Par6/aPKC polarity complex is localized to the tight junction and regulates its formation and positioning with respect to basolateral and apical membrane domains. Here we demonstrate a previously undescribed ph...
