Title: Deciphering the role of Yap4 phosphorylation under stress conditions Authors: Pereira, Jorge Abstract: The existence of molecular mechanisms of response, repair and adaptation, many of which are greatly conserved across nature, gives to the cell with the plasticity it requires to adjust to its ever-changing environment, a homeostatic event that is termed the stress response. In the budding yeast Saccharomyces cerevisiae there is a particular family of transcription factors, the Yap family, which has been shown to have a relevant role in yeast adaptation to several stress conditions. In particular, Yap1 is the major regulator of the transcriptional response to oxidative stress and Yap2 and Yap8 play important roles upon cadmium and arsenic exposure, respectively.(...)
