The Nucleosome Remodeling and Deacetylase (NuRD) complex is essential for normal development in metazoans and has direct implications in a range of human diseases. Amongst all classes of chromatin remodeling complexes, the NuRD complex has been the most recalcitrant to analysis. This is, in part, due to difficulties with producing the intact complex recombinantly. Using affinity-purification followed by mass spectrometry, we determined the stoichiometry of the NuRD complex from three cancer cell lines representing three different human tissues. We also analysed the data to determine the interactome of the NuRD complex and identified potential NuRD interactors.
