Human 14-3-3 protein zeta/delta

14.3.3 proteins are a group of highly conserved proteins that are involved in many vital cellular processes such as metabolism, protein trafficking, signal transduction, apoptosis and cell cycle regulation. 14.3.3 proteins are phospho-serine/phospho-threonine binding proteins that have a diverse array of partners including transcription factors, biosynthetic enzymes, cytoskeletal proteins, signalling molecules, apoptosis factors and tumour suppressors. The 14.3.3 family consists of 7 isoforms; beta, gamma, epsilon,sigma, zeta, tau and eta. 14.3.3 proteins are ubiquitously expressed and self assemble into homo- and heterodimers, with the exception of 14.3.3sigma, which exclusively forms homodimers and is found in cells of epithelial origin only. Each monomer contains an independent ligand-binding site, thus the 14.3.3 dimer can interact with two target proteins simultaneously. 14.3.3 proteins are highly rigid structures and ligand binding can induce conformational changes that alter the stability and/or catalytic activity of the ligand. Furthermore, 14.3.3 protein binding can physically occlude sequence-specific or structural motifs on the target that prevent molecular interactions and/or modulate the accessibility of a target protein to modifying enzymes such as kinases, phosphatases and proteases. In addition, 14.3.3 proteins can act as a scaffold molecule to anchor target proteins within close proximity of one another. 14.3.3 proteins representan integration point for proliferative, survival, apoptotic and stress signalling pathways. Members of the 14.3.3 protein family enhance the activity of many proteins with proliferative and/or survival functions, such as Raf kinases, and antagonise the activity of proteins that promote cell death and senescence, such as Bad, Bim and Bax. In contrast, 14.3.3 sigma acts as a tumour suppressor and its expression is upregulated coordinately with p53 and BRAC1. This isoform sequesters cdk1-cyclin B complexes in the cytoplasm, and thus delays cell cycle progression. 14.3.3 sigma is also a crucial regulator of translation during mitosis. Because many 14.3.3 interactions are phosphorylation dependent, 14.3.3 proteins have been integrated into the core regulatory pathways that are crucial for normal growth and development. 14.3.3 proteins are directly involved in cellular processes such as cytokinesis, cell-contact inhibition, anchorage-independent growth and cell adhesion, and it is these pathways that often become dysregulated in disease states such as cancer.
