Background of 14-3-3 protein epsilon antibody

The 14-3-3 family of proteins plays a key regulatory role in sigl transduction, checkpoint control, apoptotic and nutrient-sensing pathways. 14-3-3 proteins are highly conserved and ubiquitously expressed. There are at least seven isoforms, ß, ?, e, s, ?, t, and ? that have been identified in mammals. The initially described a and d isoforms are confirmed to be phosphorylated forms of ß and ?, respectively. Through their amino-termil a helical region, 14-3-3 proteins form homo- or heterodimers that interact with a wide variety of proteins: transcription factors, metabolic enzymes, cytoskeletal proteins, kises, phosphatases, and other sigling molecules. The interaction of 14-3-3 proteins with their targets is primarily through a phospho-Ser/Thr motif. However, binding to divergent phospho-Ser/Thr motifs, as well as phosphorylation-independent interactions, has been observed. 14-3-3 binding masks specific sequences of the target protein and therefore modulates target protein localization, phosphorylation state, stability, and molecular interactions. 14-3-3 proteins may also induce target protein conformatiol changes that modify target protein function. Distinct temporal and spatial expression patterns of 14-3-3 isoforms have been observed in development and in acute response to extracellular sigls and drugs, suggesting that 14-3-3 isoforms may perform different functions despite their sequence similarities. Several studies suggest that 14-3-3 isoforms are differentially regulated in cancer and neurological syndromes.
