Functional mapping of the N-terminal region of the yeast moonlighting protein Sis2/Hal3 reveals crucial residues for Ppz1 regulation.

The toxic effects of yeast Ppz1 phosphatase are counteracted by subcellular relocalization mediated by its regulatory subunit Hal3.

Site-directed mutagenesis results indicate mutation of ScHal3 L403 has no effect on trimerization and phosphopantothenoyl-cysteine decarboxylase function. ScHal3 L405E fails to form homotrimers, but retains the capacity to bind Cab3. Remarkably, the L405E mutation decreases Hal3's ability to interact with and to inhibit Ppz1, confirming the importance of the oligomer/monomer equilibrium in Hal3's Ppz1 regulating function.
Title: Mutations at the hydrophobic core affect Hal3 trimer stability, reducing its Ppz1 inhibitory capacity but not its PPCDC moonlighting function.
Caffeine sensitivity of the Deltappz1 disruptant is suppressed by disruption of either SAT4 or HAL5. Ppz1 controls Gln3 localization by regulating its phosphorylation state in combination with Sat4 and Hal5.
Title: Saccharomyces cerevisiae protein phosphatase Ppz1 and protein kinases Sat4 and Hal5 are involved in the control of subcellular localization of Gln3 by likely regulating its phosphorylation state.
The aim of this work was to study mechanisms which relate the activity of Ppz1p/Hal3p complex to nonsense suppression efficiency.
