Quantitative ChIP-MS analysis of histone modifications present on H3K4me1- and H3K4me3-enriched mono-nucleosomes purified from crosslinked IMR-90 cells


ABSTRACT: The INO80 complex is a chromatin remodeler that regulates DNA replication, repair, and transcription. Although the INO80 complex plays a crucial role in various chromatin-associated processes, the mechanism of its recruitment to specific genomic loci is not well understood. Here we used a native ChIP-MS approach to quantitatively profile modifications present on nucleosomes co-purified with INO80 from MNAse-digested HeLa chromatin.

DNA and histone modifications combine into characteristic patterns that demarcate functional regions of the genome<sup>1,2</sup>. While many 'readers' of individual modifications have been described<sup>3-5</sup>, how chromatin states comprising composite modification signatures, histone variants and internucleosomal linker DNA are interpreted is a major open question. Here we use a multidimensional proteomics strategy to systematically examine the interaction of around 2,000 nuclear proteins wi  ...[more]
