Regulation 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...
متن کاملThe Structural Basis for 14-3-3:Phosphopeptide Binding Specificity
The 14-3-3 family of proteins mediates signal transduction by binding to phosphoserine-containing proteins. Using phosphoserine-oriented peptide libraries to probe all mammalian and yeast 14-3-3s, we identified two different binding motifs, RSXpSXP and RXY/FXpSXP, present in nearly all known 14-3-3 binding proteins. The crystal structure of 14-3-3zeta complexed with the phosphoserine motif in p...
متن کامل14-3-3 gene expression in regenerating rat liver after 2/3 partial hepatectomy.
14-3-3 Proteins are a ubiquitous family of molecules that participate in protein kinase signaling pathways in all eukaryotic cells. Functioning as phosphoserine/phosphothreonine-binding modules, 14-3-3 proteins participate in the phosphorylation-dependent protein-protein interactions that control progression through the cell cycle, initiation and maintenance of DNA damage checkpoints, activatio...
متن کاملSpecificity of 14-3-3 isoform dimer interactions and phosphorylation.
Proteins that interact with 14-3-3 isoforms are involved in regulation of the cell cycle, intracellular trafficking/targeting, signal transduction, cytoskeletal structure and transcription. Recent novel roles for 14-3-3 isoforms include nuclear trafficking the direct interaction with cruciform DNA and with a number of receptors, small G-proteins and their regulators. Recent findings also show t...
متن کاملThe 14-3-3 gene par-5 is required for germline development and DNA damage response in Caenorhabditis elegans.
14-3-3 proteins have been extensively studied in organisms ranging from yeast to mammals and are associated with multiple roles, including fundamental processes such as the cell cycle, apoptosis and the stress response, to diseases such as cancer. In Caenorhabditis elegans, there are two 14-3-3 genes, ftt-2 and par-5. ftt-2 is expressed only in somatic lineages, whereas par-5 expression is dete...
