• There are 7 known mammalian 14-3-3 isoforms epsilon, beta, zeta, gamma, theta, tau and they play important roles in many biological activities by binding to and altering the subcellular localization and/or stability of key molecules in various signaling cascades
• 14-3-3 sigma was originally characterized as a human mammary epithelium marker and later rediscovered as an important molecule for cell cycle checkpoint regulation
• Recently it has been reported that 14-3-3 sigma may serve as a prognosis marker predicting survival of pancreatic cancer patient treatment
• 14-3-3 sigmais the only 14-3-3 isoform induced by the tumor suppressor protein p53, in response to g-irradiation and other DNA-damaging agents
• 14-3-3 sigmais a p53-regulated inhibitor of G2/M progression and acts as a tumor suppressor gene that is inactivated by methylation of its 5' CpG islands in epithelial tumor cells
• Two isoforms of human 14-3-3 sigma are produced by alternative splicing.
