A rate threshold mechanism regulates MAPK stress signaling and survival.
Title: A rate threshold mechanism regulates MAPK stress signaling and survival.
PTP2 and MSG5 are key regulatory PPases that prevent over-activation of the calcium-induced signaling cascade under the parallel control of the SLT2 and calcineurin pathways.
Title: Functionally redundant protein phosphatase genes PTP2 and MSG5 co-regulate the calcium signaling pathway in Saccharomyces cerevisiae upon exposure to high extracellular calcium concentration.
Data discovered that six non-essential protein kinase (PKase) disruptions (Deltabck1, Deltamkk1, Deltaslt2/Deltampk1, Deltamck1, Deltassk2 and Deltayak1) suppressed the Cas-phenotype of the Deltaptp2 Deltamsg5 double disruptant.
Title: Identification of protein kinase disruptions as suppressors of the calcium sensitivity of S. cerevisiae Deltaptp2 Deltamsg5 protein phosphatase double disruptant.
These findings suggest that both Ptp2p and Msg5p are involved in the G1 to S transition and vacuole morphogenesis possibly through their regulation of Slt2 pathway.
Title: Yeast protein phosphatases Ptp2p and Msg5p are involved in G1-S transition, CLN2 transcription, and vacuole morphogenesis.
The Hog 1 common docking & PBD-2 docking sites are also involved in the specific interaction between Hog1 & Ptp2 and govern the dynamic dephosphorylation of activated Hog1.
Title: Two adjacent docking sites in the yeast Hog1 mitogen-activated protein (MAP) kinase differentially interact with the Pbs2 MAP kinase kinase and the Ptp2 protein tyrosine phosphatase.
