This entry represents the N-terminal domain of SWI/SNF and RSC complexes subunit Ssr4 from S. pombe, a essential member of the chromatin structure remodelling complex (RSC) and the SWI/SNF complex [1,2]. The structure of this domain revealed that it has a novel fold comprising an antiparallel beta-sheet of seven strands with alpha-helices on one side and random coil on the other [2]. It contains the highly conserved motif WxxxxxPxxGxxxxxxxxxxxxxxxDG. RSC is involved in transcription regulation and nucleosome positioning which controls, particularly, membrane and organelle development genes. The ATP-dependent chromatin remodelling complex SWI/SNF is required for the positive and negative regulation of gene expression of a large number of genes through the regulation of nucleosome remodelling [1].
