In vitro and in cell analysis of chemically synthesized histone H2A with multiple modifications†
Abstract
The chemical synthetic route to histone H2A is described. An H2A–H2B dimer, histone octamer, and nucleosome were reconstituted with the synthetic H2A. Fluorescein-labeled H2A and multiply modified H2A, which has three different posttranslational modifications, were also synthesized, and applied to live-cell imaging and in vitro nucleosome stability assays, respectively.
