PDBsumstructure summary

14-3-3 proteins are a family of conserved regulatory molecules that are expressed in all eukaryotic cells. 14-3-3 proteins have the ability to bind a multitude of functionally diverse signaling proteins, including kinases, phosphatases, and transmembrane receptors. More than 200 signaling proteins have been reported as 14-3-3 ligands.

Elevated amounts of 14-3-3 protein in cerebrospinal fluid are usually a sign of rapid neurodegeneration; a common indicator of Creutzfeldt–Jakob disease.[2]
