Trehalases are important highly conserved enzymes found in a wide variety of organisms and are responsible for the hydrolysis of trehalose that serves as a carbon and energy source as well as a universal stress protectant. Emerging evidence indicates that the enzymatic activity of the neutral trehalase Nth1 in yeast is enhanced by 14-3-3 protein binding in(More)
The FOXO forkhead transcription factors are potent transcriptional activators involved in a wide range of key biological processes. In this work, the real-time kinetics of the interaction between the FOXO4-DNA binding domain (FOXO4-DBD) and the DNA was studied by using surface plasmon resonance (SPR). SPR analysis revealed that the interaction between(More)
The role of 14-3-3 proteins in the regulation of FOXO forkhead transcription factors is at least 2-fold. First, the 14-3-3 binding inhibits the interaction between the FOXO and the target DNA. Second, the 14-3-3 proteins prevent nuclear reimport of FOXO factors by masking their nuclear localization signal. The exact mechanisms of these processes are still(More)
