14-3-3 sigma (stratifin, SFN, epithelial cell marker protein 1) is a member of a highly conserved family of 14-3-3 proteins that are present in all eukaryotic organisms. 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 sigma is 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 sigma is a p53-regulated inhibitor of G2/M progression and acts as a tumor suppressor gene that is inactivated by methylation of its 5 ft. CpG islands in epithelial tumor cells. Two isoforms of human 14-3-3 sigma are produced by alternative splicing.
