14-3-3-Pred: improved methods to predict 14-3-3-binding phosphopeptides
MOTIVATION The 14-3-3 family of phosphoprotein-binding proteins regulates many cellular processes by docking onto pairs of phosphorylated Ser and Thr residues in a constellation of intracellular targets. Therefore, there is a pressing need to develop new prediction methods that use an updated set of 14-3-3-binding motifs for the identification of new 14-3-3 targets and to prioritize the downstr...
متن کاملA fusicoccin binding protein belongs to the family of 14-3-3 brain protein homologs.
The fusicoccin binding protein (FCBP) is a highly conserved plasma membrane protein present in all higher plants tested thus far. It exhibits high- and low-affinity binding for the fungal toxin fusicoccin (FC). We purified the active FCBP from a fraction highly enriched in plasma membrane by selective precipitation and anion exchange chromatography. After SDS-PAGE, the two FCBP subunits of 30 a...
متن کاملThe 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 کاملModulators of 14-3-3 Protein-Protein Interactions.
Direct interactions between proteins are essential for the regulation of their functions in biological pathways. Targeting the complex network of protein-protein interactions (PPIs) has now been widely recognized as an attractive means to therapeutically intervene in disease states. Even though this is a challenging endeavor and PPIs have long been regarded as "undruggable" targets, the last tw...
متن کامل14-3-3 inhibits the Dictyostelium myosin II heavy-chain-specific protein kinase C activity by a direct interaction: identification of the 14-3-3 binding domain.
Myosin II heavy chain (MHC) specific protein kinase C (MHC-PKC), isolated from Dictyostelium discoideum, regulates myosin II assembly and localization in response to the chemoattractant cyclic AMP. Immunoprecipitation of MHC-PKC revealed that it resides as a complex with several proteins. We show herein that one of these proteins is a homologue of the 14-3-3 protein (Dd14-3-3). This protein has...
