14-3-3 Proteins are no more a mystery
Daniela Berg, Carsten
Holzman and Olaf Riess shed light on a mysterious class of protein (14-3-3 Proteins in the
Nervous System, Nature Review Neuroscience 4, 752-762, 2003). Beautifully illustrated,
fully informative and well balanced, this review article is a precious tool for
the knowledge of this new class of signalling proteins, initially described as
activators of neurotransmitter synthesis. As the abstract reads, 14-3-3
proteins are abundantly expressed in the brain and have been detected in the
cerebrospinal fluid of patients with different neurological disorders. Although
the function of this family of highly conserved proteins is not completely
known, recent evidence indicates their involvement in multiple cellular
processes. By their interaction with more than 100 binding partners, 14-3-3
proteins modulate the action of proteins that are involved in cell cycle and
transcriptional control, signal transduction, intracellular trafficking and
regulation of ion channels. The study of some of these interactions is shedding
light on the role of 14-3-3 proteins in processes such as apoptosis and
neurodegeneration.
We recommend as further
readings the articles marked by the authors in the reference list.
