SWI/SNF-like ATP-dependent chromatin remodeler; involved in silencing at the MAT locus, telomeres and centromeres; enriched at centromeres and required to promote correct chromatin structure around centromeres and at the boundary element of silent mating type loci; recruited to DNA double-strand breaks (DSBs) where it promotes 5' strand resection; role in meiotic DSB resection and recombination; potential Cdc28p substrate
