Phenotypic Suppression
A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
The homologous recombination machinery modulates the formation of RNA-DNA hybrids and associated chromosome instability.
Genome instability in yeast and mammals is caused by RNA-DNA hybrids that form as a result of defects in different aspects of RNA biogenesis. We report that in yeast mutants defective for transcription repression and RNA degradation, hybrid formation requires Rad51p and Rad52p. These proteins normally promote DNA-DNA strand exchange in homologous recombination. We suggest they also directly promote the ... [more]
