14-3-3 Proteins: a window for a deeper understanding of fungal metabolism and development
- 50 Downloads
Isoforms of 14-3-3 proteins, similar to their highly conserved homologs in mammals and plants, are both transcriptionally and functionally affected by their extracellular and intracellular environments. These proteins bind to phosphorylated client proteins to modulate their functions in fungi. Since phosphorylation regulates a plethora of different physiological responses in organisms, 14-3-3 proteins play roles in multiple physiological functions, including those controlling metabolisms, cell division, and responses to environmental stimulation. These proteins could also modulate signaling pathways that transduce inputs from the environment and downstream proteins that elicit physiological responses. Increasing evidence supports a prominent role for 14-3-3 proteins in regulating development and metabolism at various levels. In this review, we first provide a brief summary of the molecular structure of 14-3-3 proteins. Second, we discuss the potential roles of 14-3-3 proteins in the regulation of development and metabolism. Third, we review the roles of 14-3-3 proteins in the regulation of their binding partners, including receptors, protein kinases, and some protein kinase substrates. Finally, this review examines recent advances that further elucidate the role of 14-3-3 proteins in signaling transduction in response to environmental stress.
