<n0:ComplexDefinition xmlns:n0="http://ncicb.nci.nih.gov/xml/owl/EVS/ComplexProperties.xsd#"><n0:def-definition>A motif common in chromatin remodeling factors. It consists of approximately 110 amino acids in a left-handed up-and-down four helix bundle with a left handed twist. A hydrophobic pocket in the bromodomain creates an acetyl-lysine binding domain. Bromodomain-containing proteins may recruit remodeling complexes to acetylated chromatin regions.</n0:def-definition><n0:def-source>NCI</n0:def-source></n0:ComplexDefinition>
