Role of Ssd1 in modulating protein abundance in aneuploid wild yeast


ABSTRACT: We discovered that wild yeast strains can tolerate extra chromosomes, a condition known as aneuploidy, whereas well-studied laboratory strains cannot. Understanding why some cells can tolerate aneuploidy and others cannot could have far-reaching impact, as for example, 85% of solid tumors are aneuploidy and often benefit from extra chromosomes, and thus identifying mechanisms of aneuploidy sensitization could have therapeutic applications.

Aneuploidy is highly detrimental during development yet common in cancers and pathogenic fungi - what gives rise to differences in aneuploidy tolerance remains unclear. We previously showed that wild isolates of <i>Saccharomyces cerevisiae</i> tolerate chromosome amplification while laboratory strains used as a model for aneuploid syndromes do not. Here, we mapped the genetic basis to Ssd1, an RNA-binding translational regulator that is functional in wild aneuploids but defective in laboratory s  ...[more]
