Recognizes 14-3-3 eta in all mammals. It is a member of the 14-3-3 family which consists of 30 kDa proteins that are involved in multiple protein kinase signaling pathways, regulation of cell cycle progression, cytoskeletal structure, transcription, intracellular trafficking and targeting. Protein interactions with 14-3-3 show distinct preference for it’s different isoforms and are regulated by phosphorylation of both 14-3-3 and the bound protein.
14-3-3 eta is expressed principally in the brain although it is expressed at low levels in other tissues. The protein binds alpha-synuclein, forming part of lewy bodies in parkinsons disease and has been linked to early-onset schizophrenia. The eta isoform binds both gremlin 1, which is overexpressed in human cancers, and the DAL-1/Protein 4.1B tumour suppressor. Furthermore the glucocortcoid receptor is positively regulated by 14-3-3- eta.

Members of the 14-3-3 family of proteins are highly conserved proteins, localized in neurons, and are axonally transported to the nerve terminals. They are also present, at lower levels, in various other eukaryotic tissues. 14-3-3 proteins appear to play important roles in a variety of signal transduction pathways, including those involved in cell cycle regulation and cell survival. Because 14-3-3 proteins bind to specific phosphoserine-containing sequences they are likely to have an important role in signaling pathways mediated by serine/threonine protein kinases. Evidence indicates 14-3-3 is required for Raf 1 kinase activity and phosphorylation among many other functions.
