The third family of SWI-like ATP-dependent chromatin-remodelling complexes is the CHD family. Theses complexes contain members of the CHD family of ATPases, which comprises nine chromodomain-containing members (see ref. 61 for a review) (Table 2). CHD proteins are broadly classified into three subfamilies based on their constituent domains: subfamily I (CHD1 and CHD2), subfamily II (CHD3 and CHD4) and subfamily III (CHD5, CH6, CHD7, CHD8 and CHD9).
