The X-ray crystal structure of the N-terminal domain of Ssr4, a Schizosaccharomyces pombe chromatin-remodelling protein.

ABSTRACT: Ssr4 is a yeast protein from Schizosaccharomyces pombe and is an essential part of the chromatin-remodelling [SWI/SNF and RSC (remodelling the structure of chromatin)] complexes found in S. pombe. These complexes (or their homologues) regulate gene expression in eukaryotic organisms, affecting a large number of genes both positively and negatively. The downstream effects are seen in development, and in humans have implications for disease such as cancer. The chromatin structure is altered by modifying the DNA-histone contacts, thus opening up or closing down sections of DNA to specific transcription factors that regulate the transcription of genes. The Ssr4 sequence has little homology to other sequences in the Protein Data Bank, so the structure was solved using an iodine derivative with
