14-3-3 protein

Function 14-3-3 proteins (PRS) are conserved regulatory proteins which bind to a multitude of signaling proteins like kinases phosphatases and transmembrane receptors. The name 14-3-3 derives from their elution pattern via chromatography. Disease Elevated levels of PRS are found in patients with Creutzfeld-Jakob disease (CJD). PRS are associated with Parkinson Disease (PD) and with Alzheimer Disease (AD) based on their localization and their binding to PD and AD-associated proteins. Relevance PRS are tested as biomarkers for CJD, PD and AD. Structural highlights PRS are homo- and heterodimers containing . (3 helices of chain A are in red and 3 helices of chain B are in magenta). .
