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 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 کاملDynamic interactions between 14-3-3 proteins and phosphoproteins regulate diverse cellular processes.
14-3-3 proteins exert an extraordinarily widespread influence on cellular processes in all eukaryotes. They operate by binding to specific phosphorylated sites on diverse target proteins, thereby forcing conformational changes or influencing interactions between their targets and other molecules. In these ways, 14-3-3s 'finish the job' when phosphorylation alone lacks the power to drive changes...
متن کاملInteraction between Rho GTPases and 14-3-3 Proteins
The Rho GTPase family accounts for as many as 20 members. Among them, the archetypes RhoA, Rac1, and Cdc42 have been the most well-characterized. Like all members of the small GTPases superfamily, Rho proteins act as molecular switches to control cellular processes by cycling between active, GTP-bound and inactive, GDP-bound states. The 14-3-3 family proteins comprise seven isoforms. They exist...
متن کاملPhosphorylation-dependent 14-3-3 protein interactions regulate CFTR biogenesis
Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP/protein kinase A (PKA)-regulated chloride channel whose phosphorylation controls anion secretion across epithelial cell apical membranes. We examined the hypothesis that cAMP/PKA stimulation regulates CFTR biogenesis posttranslationally, based on predicted 14-3-3 binding motifs within CFTR and forskolin-induced CFTR expression...
