چکیده انگلیسی
The RhoGAP Rgd1p is involved in different signal transduction pathways in Saccharomyces cerevisiae through its regulatory activity upon the Rho3 and Rho4 GTPases. The rgd1Î mutant, which presents a mortality at the entry into the stationary phase in minimal medium, is sensitive to medium acidification caused by biomass augmentation. We showed that low-pH shock leads to abnormal intracellular acidification of the rgd1Î mutant. Transcriptional regulation of RGD1 was studied in several stress conditions and we observed an activation of RGD1 transcription at low pH and after heat and oxidative shocks. The transcription level at low pH and after heat shock was demonstrated to depend on the STRE box located in the RGD1 promoter. The general stress-activated transcription factors Msn2p and Msn4p as well as the HOG pathway were shown to mainly act on the basal RGD1 transcriptional level in normal and stress conditions.
