Biochem./physiol. Wirkung

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.[1] 14-3-3σ proteins play a critical role in signal transduction pathways and cell cycle regulation. 14-3-3σ is the only 14-3-3 isoform induced by the tumor suppressor protein p53, in response to γ-irradiation and other DNA-damaging agents.[2] 14-3-3σ is a p53-regulated inhibitor of G2/M progression[3] and acts as a tumor suppressor gene that is inactivated by methylation of its 5′ CpG islands in epithelial tumor cells.

14-3-3 sigma is induced by tumor suppressor protein p53 in response to DNA damage. p53 can directly transactivate the expression of 14-3-3 sigma to cause a G(2) cell cycle arrest when cell DNA is damaged. The expression of 14-3-3 sigma

Exposure of colorectal cancer (CRC) cells to ionizing radiation results in a cell-cycle arrest in G1 and G2. The G1 arrest is due to p53-mediated induction of the cyclin-dependent kinase inhibitor p21WAF1/CIP1/SDI1, but the basis for the G2 arrest is
