BAH, or Bromo Adjacent Homology domain, as present in polybromo and yeast RSC1/2. The human polybromo protein (BAF180) is a component of the SWI/SNF chromatin-remodeling complex PBAF. It is thought that polybromo participates in transcriptional regulation. Saccharomyces cerevisiae RSC1 and RSC2 are part of the 15-subunit nucleosome remodeling RSC complex. BAH domains are found in a variety of proteins playing roles in transcriptional silencing and the remodeling of chromatin. It is assumed that in most or all of these instances the BAH domain mediates protein-protein interactions.
