A novel 15-subunit complex with the capacity to remodel the structure of chromatin, termed RSC, has been isolated from S. cerevisiae on the basis of homology to the SWI/SNF complex. At least three RSC subunits are related to SWI/SNF polypeptides: Sth1p, Rsc6p, and Rsc8p are significantly similar to Swi2/Snf2p, Swp73p, and Swi3p, respectively, and were(More)
The detection of a DNA double-strand break (DSB) is necessary to initiate DSB repair. Several proteins, including the MRX/N complex, Tel1/ATM (ataxia telangiectasia mutated), and Mec1/ATR (ATM and Rad3 related), have been proposed as sensors of DNA damage, yet how they recognize the breaks is poorly understood. DSBs occur in the context of chromatin,(More)
