A common SSD1 truncation is toxic to cells entering quiescence and promotes sporulation.

Ssd1p is an RNA binding protein in Saccharomyces cerevisiae that plays an important role in cell division, cell fate decisions, stress response and virulence. Lab strain W303 encodes the terminal truncation ssd1-2, which is typically interpreted to be a loss of function allele. We have shown that ss...

description Ssd1p is an RNA binding protein in Saccharomyces cerevisiae that plays an important role in cell division, cell fate decisions, stress response and virulence. Lab strain W303 encodes the terminal truncation ssd1-2, which is typically interpreted to be a loss of function allele. We have shown that ssd1-2 is toxic to mpt5-Δ mutants and to diploids entering stationary phase and quiescence. The ssd1-Δ null shows no toxicity, indicating that ssd1-2 is disrupting an essential function that does not solely require Ssd1p. ssd1-2 cells are also more sensitive to stress than ssd1-Δ . These phenotypes are recessive to SSD1-1 . In contrast, ssd1-2 plays a dominant role in promoting sporulation.
