Biochem/physiol Actions

14-3-3 proteins are involved in a multitude of biological processes and play a regulatory role in processes such as apoptotic cell death, mitogenic signal transduction, and cell cycle control. Co-immunoprecipitation experiments demonstrate the interaction of 14-3-3 τ/θ adaptor protein with various proteins (UCP3, PKCζ). 14-3-3 τ/θ is involved in cell cycle arrest and cellular differentiation. 14-3-3 τ/θ plays an active role in mediating Vpr-induced cell cycle arrest in human T cells.
