Although immune mechanisms have been described for Peyer’s patch function, in discriminating food nutrients and commensal microflora from pathogenic challenge, an understanding of gene expression patterns associated with normal intestinal homeostasis is lacking. The effects of commensal bacterial co...

A new site of methylation was identified on histone H3 K42 in Saccharomyces cerevisiae. Mutations were engineered at this site to mimic either a constitutively modified state, K42L, or a constitutively unmodified state, K42Q in addition to an alanine substitution. K42A. The effects of these mutation...

The structural integrity of the nucleosome is central to regulation of DNA metabolism and transcription. We describe a library of 486 systematic histone H3 and H4 substitution and deletion mutants in Saccharomyces cerevisiae that probe the contribution of each residue to nucleosome function and can ...
