Inhibition of the Arabidopsis salt overly sensitive pathway by 14-3-3 proteins.
The Salt Overly Sensitive (SOS) pathway regulates intracellular sodium ion (Na(+)) homeostasis and salt tolerance in plants. Until recently, little was known about the mechanisms that inhibit the SOS pathway when plants are grown in the absence of salt stress. In this study, we report that the Arabidopsis thaliana 14-3-3 proteins λ and κ interact with SOS2 and repress its kinase activity. Growt...
متن کاملInhibition of calcium/calmodulin-dependent protein kinase kinase by protein 14-3-3.
Intracellular calcium concentrations regulate diverse cellular events including cytoskeletal dynamics, gene transcription, and synaptic plasticity. The calcium signal is transduced in part by the calcium/calmodulin-dependent protein kinase (CaMK) cascade that is comprised of CaMK kinase (CaMKK) and its primary downstream substrates, CaMKI and CaMKIV. The CaMK cascade also participates in cross-...
متن کامل14-3-3 proteins are required for the inhibition of Ras by exoenzyme S.
14-3-3 proteins play a regulatory role and participate in both signal transduction and checkpoint control pathways. 14-3-3 proteins bind phosphoserine ligands, such as Raf-1 kinase and Bad, by recognizing the phosphorylated consensus motif, Arg-Ser-Xaa-pSer-Xaa-Pro (where 'Xaa' represents 'any residue', and 'pSer' is 'phosphoserine'). However, 14-3-3 proteins must bind unphosphorylated ligands,...
متن کاملRegulation of transcription by Saccharomyces cerevisiae 14-3-3 proteins.
14-3-3 proteins form a family of highly conserved eukaryotic proteins involved in a wide variety of cellular processes, including signalling, apoptosis, cell-cycle control and transcriptional regulation. More than 150 binding partners have been found for these proteins. The yeast Saccharomyces cerevisiae has two genes encoding 14-3-3 proteins, BMH1 and BMH2. A bmh1 bmh2 double mutant is unviabl...
متن کاملRegulation of Arabidopsis 14 - 3 - 3 gene expression by GABA
The function in plants of the non-protein amino acid, γ-aminobutyric acid (GABA) is poorly understood. In this study, we show that GABA down-regulates the expression of a large subset of 14-3-3 gene family members in Arabidopsis thaliana seedlings in a calcium, ethylene and abscisic acid-dependent manner. Gene expression is not affected when seedlings are supplied with glutamate, a precursor of...
