The tumour suppressor CHD5 forms a NuRD-type chromatin remodelling complex.

ABSTRACT: Eukaryotic gene expression is developmentally regulated, in part by chromatin remodelling, and its dysregulation has been linked to cancer. CHD5 (chromodomain helicase DNA-binding protein 5) is a tumour suppressor gene (TSG) that maps to a region of consistent deletion on 1p36.31 in neuroblastomas (NBs) and other tumour types. CHD5 encodes a protein with chromatin remodelling, helicase and DNA-binding motifs that is preferentially expressed in neural and testicular tissues. CHD5 is highly homologous to CHD3 and CHD4, which are the core subunits of nucleosome remodelling and deacetylation (NuRD) complexes. To determine if CHD5 forms a similar complex, we performed studies on nuclear extracts from NBLS, SY5Y (both with endogenous CHD5 expression), NLF (CHD5 null) and NLF cells stably transfe
