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 14-3-3 sigma, 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 represent an integration point for proliferative, survival, apoptotic and stress signalling pathways.

14-3-3 beta/alpha is a family member of 14-3-3 proteins, which has been implicated as a negative regulator of osteogenesis. 14-3-3 beta/alpha also blocks the nuclear translocation of the phosphorylated form of SRPK2 and antagonizes its stimulatory effect on cyclin D1 expression resulting in blockage of neuronal apoptosis elicited by SRPK2.
