The Ppz protein phosphatases regulate Trk-independent potassium influx in yeast.

FEBS letters - 3 Dec 2004

Ruiz Amparo, del Carmen Ruiz María, Sánchez-Garrido Miguel Angel, Ariño Joaquín, Ramos José

Abstract excerpt

The Ppz protein phosphatases have been recently shown to negatively regulate the major potassium transport system in the yeast Saccharomyces cerevisiae, encoded by the TRK1 and TRK2 genes. We have found that, in the absence of the Trk system, Ppz mutants require abnormally high concentrations of potassium to proliferate. This can be explained by the observation that trk1 trk2 ppz1 or trk1 trk2 ppz1 ppz2 strains...
