In vitro chromatin assembly - A quantitative proteomic analysis of in vitro assembled chromatin

Here, we use LC-MSMS and SWATH-MS to describe the kinetics of in vitro assembled chromatin supported by an embryo extract prepared from preblastoderm Drosophila melanogaster embryos. This system allows easy manipulation of distinct aspects of chromatin assembly such as post-translational histone modifications, the levels of histone chaperones and the concentration of distinct DNA binding factors. Our findings support the idea that chromatin assembly factors and factors important for chromatin structure bind chromatin an ordered manner, which is -at least in part- regulated by histone deacetylation.
