The 14-3-3 proteins
So what’s so interesting about them? In 1996 14-3-3 was found to bind to a variety of oncoproteins including Raf-1, polyoma middle T, and Bcr-Abl. Since then the 14-3-3 proteins have been shown to bind to a wide variety of proteins involved in signal transduction, cell cycle and apoptosis. These proteins include Cdc25, NFAT, Bad, Cbl, A20, PI 3-kinase, IRS-1, MEKK, p130Cas, glucocorticoid recep...
متن کامل14-3-3 proteins in apoptosis.
The once obscure members of the 14-3-3 protein family play significant roles in the determination of cell fate. By inhibiting the pro-apoptotic BAD (Bcl-2-antagonist of cell death) and the transcription factor FKHRL-1, 14-3-3 displays important anti-apoptotic characteristics. To date, five points of interaction of 14-3-3 with the apoptotic machinery have been identified. How these interactions ...
متن کاملOsELF3-1, an Ortholog of Arabidopsis EARLY FLOWERING 3, Regulates Rice Circadian Rhythm and Photoperiodic Flowering
Arabidopsis thaliana early flowering 3 (ELF3) as a zeitnehmer (time taker) is responsible for generation of circadian rhythm and regulation of photoperiodic flowering. There are two orthologs (OsELF3-1 and OsELF3-2) of ELF3 in rice (Oryza sativa), but their roles have not yet been fully identified. Here, we performed a functional characterization of OsELF3-1 and revealed it plays a more predomi...
متن کاملLight modulated activity of root alkaline/neutral invertase involves the interaction with 14-3-3 proteins.
Alkaline/neutral invertases (A/N-Invs) are now recognized as essential proteins in plant life. They catalyze the irreversible breakdown of sucrose into glucose and fructose and thus supply the cells with energy as well as signaling molecules. In this study we report on a mechanism that affects the activity of the cytosolic invertase AtCINV1 (At-A/N-InvG or AT1G35580). We demonstrate that Ser547...
متن کامل14-3-3 Proteins Participate in Light Signaling through Association with PHYTOCHROME INTERACTING FACTORs
14-3-3 proteins are regulatory proteins found in all eukaryotes and are known to selectively interact with phosphorylated proteins to regulate physiological processes. Through an affinity purification screening, many light-related proteins were recovered as 14-3-3 candidate binding partners. Yeast two-hybrid analysis revealed that the 14-3-3 kappa isoform (14-3-3κ) could bind to PHYTOCHROME INT...
