Regulation 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 tuberous sclerosis complex (TSC) function by 14-3-3 proteins.
Tuberous sclerosis complex (TSC) is a genetic disorder characterized by seizures, mental disability, renal dysfunction and dermatological abnormalities. The disease is caused by inactivation of either hamartin or tuberin, the products of the TSC1 and TSC2 tumour-suppressor genes. Hamartin and tuberin form a complex and antagonise phosphoinositide 3-kinase/protein kinase B/target of rapamycin si...
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...
متن کاملPlant metabolism: Enzyme regulation by 14-3-3 proteins
14-3-3 proteins have been found to regulate the plant enzyme nitrate reductase by reversible phosphoserine binding. Plant plasma-membrane H(+)-ATPases, transporters that are activated by the phytotoxin fusicoccin, appear to be regulated in a similar fashion.
متن کامل14-3-3 isotypes facilitate coupling of protein kinase C-zeta to Raf-1: negative regulation by 14-3-3 phosphorylation.
14-3-3 Proteins may function as adapters or scaffold in signal-transduction pathways. We found previously that protein kinase C-zeta (PKC-zeta) can phosphorylate and activate Raf-1 in a signalling complex [van Dijk, Hilkmann and van Blitterswijk (1997) Biochem. J. 325, 303-307]. We report now that PKC-zeta-Raf-1 interaction is mediated by 14-3-3 proteins in vitro and in vivo. Co-immunoprecipita...
