Mutations conferring synthetic lethality in combination with null mutations in CAP2, the gene encoding the beta subunit of capping protein of Saccharomyces cerevisiae, were obtained in a colony color assay. Monogenic inheritance was found for four mutations, which were attributed to three genetic loci. One mutation, sac6-69, is in the gene encoding fimbrin, another actin-binding protein, which was expected because null mutations in SAC6 and CAP2 are known to be synthetic-lethal. The other two loci were designated slc for synthetic lethality with cap2. These loci include the mutations slc1-66, slc1-87 and slc2-107. The slc mutations are semi-dominant, as shown by incomplete complementation in slc/SLC cap2/cap2 heterozygotes. The slc mutations and sac6-69 interact with each other, as shown by enhanced phenotypes in diheterozygotes. Moreover, the haploid slc2-107 sac6-69 double mutant is inviable. In a CAP2 background, the slc mutations lead to temperature and osmotic sensitivity. They alter the distribution of the actin cytoskeleton, including deficits in the presence of actin cables and the polarization of cortical actin patches. The slc mutations also lead to a pseudomycelial growth pattern. Together these results suggest that slc1 and slc2 encode components of the actin cytoskeleton in yeast and that the actin cytoskeleton can regulate the patterns of growth.
