Regulation of ENA1 Na(+)-ATPase gene expression by the Ppz1 protein phosphatase is mediated by the calcineurin pathway.

Eukaryotic cell - 1 Oct 2003

Ruiz Amparo, Yenush Lynne, Ariño Joaquín

Abstract excerpt

Saccharomyces cerevisiae strains lacking the Ppz1 protein phosphatase are salt tolerant and display increased expression of the ENA1 Na(+)-ATPase gene, a major determinant for sodium extrusion, while cells devoid of the similar Ppz2 protein do not show these phenotypes. However, a ppz1 ppz2 mutant displays higher levels of ENA1 expression than the ppz1 strain. We show here that the increased activity of the ENA1...
