The functions and the characteristic domain architecture of the ATPase subunit of chromatin remodelling families from animal systems: chromatin remodellers from yeast and animal systems are classified into four families based on split ATPase domains and the characteristic flanking domains unique for each class. The callout boxes represent the functions that have been assigned to each family of the remodeller by the biochemical and genetic approaches from animal systems and yeast. The bottom panel indicates the domain architecture of each of these families that classifies them into the specific class of the remodeller as described by Clapier and Cairns (2009).
