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 کامل14-3-3 protein targets misfolded chaperone-associated proteins to aggresomes.
The aggresome is a key cytoplasmic organelle for sequestration and clearance of toxic protein aggregates. Although loading misfolded proteins cargos to dynein motors has been recognized as an important step in the aggresome formation process, the molecular machinery that mediates the association of cargos with the dynein motor is poorly understood. Here, we report a new aggresome-targeting path...
متن کامل14-3-3 proteins: potential roles in vesicular transport and Ras signaling in Saccharomyces cerevisiae.
Deletion of the clathrin heavy-chain gene, CHC1, in the budding yeast Saccharomyces cerevisiae results in growth, morphological, and membrane trafficking defects, and in some strains chc1-delta is lethal. A previous study identified five genes which, in multicopy, rescue inviable strains of Chc- yeast. Now we report that one of the suppressor loci, BMH2/SCD3, encodes a protein of the 14-3-3 fam...
متن کاملNeuroprotective Function of 14-3-3 Proteins in Neurodegeneration
14-3-3 proteins are abundantly expressed adaptor proteins that interact with a vast number of binding partners to regulate their cellular localization and function. They regulate substrate function in a number of ways including protection from dephosphorylation, regulation of enzyme activity, formation of ternary complexes and sequestration. The diversity of 14-3-3 interacting partners thus ena...
