Abstract:
:The RSC complex of Saccharomyces cerevisiae is closely related to the SWI/SNF complex. Both complexes are involved in remodeling chromatin structure and they share conserved components. The RSC proteins Sth1, Rsc8/Swh3, Sfh1 and Rsc6 are homologs of the SWI/SNF proteins Swi2/Snf2, Swi3, Snf5 and Swp73 respectively. To investigate the RSC complex, we isolated a temperature-sensitive swh3 allele. A screen for multicopy suppressors yielded plasmids carrying the RSC6 and MAK31 loci. RSC6 also suppressed the formamide sensitivity of a strain with a C-terminal truncation of SWH3 . We show that Swh3 and Rsc6 fusion proteins interact in the two-hybrid system and that the swh3-ts mutation impairs this interaction. Finally, bacterially produced Swh3 and Rsc6 fusion proteins interact in vitro , supporting the genetic evidence for direct interaction between Swh3 and Rsc6 in vivo . We have previously shown that Swh3 also interacts with Sth1. These findings, together with the conservation of these proteins in the SWI/SNF complex and in mammalian SWI/SNF-related complexes, strongly suggest that these proteins form a structural core for the complex.
