Stationary-phase induction of GLR1 expression is mediated by the yAP-1 transcriptional regulatory protein in the yeast Saccharomyces cerevisiae.

abstract：:Cells invest a significant amount of their energy synthesizing proteins, and a large portion of the energy expenditure goes into making ribosomes, the RNA-protein machines at the centre of translation. When ribosomes are damaged in a cell, i.e. during stressful conditions, cells must first recognize the damage and the...
