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. 14-3-3η binds various proteins such as the MTLX-2 transcription factor as well as the DNA binding domain of Miz1 transcription factor. 14-3-3η also binds the glucocorticoid receptor, functioning as a positive regulator in the glucocorticoid signaling pathway. 14-3-3η is expressed and regulated in nerve cells.

Physical form

Supplied as a 0.2 μm filtered solution in 50 mM Tris-HCl, pH 7.6, 1 mM EDTA, 1 mM DTT, and 20% glycerol (w/v).

The glucocorticoid receptor (GR), a member of the nuclear receptor superfamily, mediates the effects of glucocorticoids. It is known that 14-3-3 family proteins interact with GR and regulate its transcriptional activity. They also bind to several molecules and influence many

The 14-3-3 proteins constitute a family of highly conserved and broadly expressed multifunctional polypeptides that are involved in a variety of important cellular processes that include cell cycle progression, growth, differentiation, and apoptosis. Although the exact cellular function(s) of 14-3-3

The transcription factor Miz1 is required for DNA-damage-induced cell-cycle arrest. We have now identified 14-3-3eta as a gene that inhibits Miz1 function through interaction with its DNA binding domain. Binding of 14-3-3eta to Miz1 depends on phosphorylation by Akt and
