14-3-3 Induced Apoptosis

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


Apoptosis is a physiological process of cell death that plays a critical role in normal development as well as in the pathophysiology of a variety of diseases. The fundamental cellular mechanism behind apoptosis is due to a balance between anti-apoptotic and pro-apoptotic factors, which may be shifted by extracellular signals. 14-3-3 proteins play an important suppressing role in several apoptotic pathways in animals. These are a family of abundant, widely expressed 28-33-kDa acidic polypeptides that spontaneously self-assemble as dimmers. The 14-3-3 family of proteins mediates signal transduction by binding to phosphoserine-containing proteins. There are at least seven distinct genes for 14-3-3 in vertebrates, giving rise to nine isotypes (Alpha, Beta, Gamma, Delta, Epsilon, Eta, Sigma, Tau, and Zeta, with Alpha [...]
