Abstract

Histone H4 lysine acetylation regulated by MOF (males absent on the first) was initially discovered as a dosage compensation epigenetic mark. Recent studies have revealed, however, that the epigenetic mark has a critical role in cellular function both during oogenesis as well as oncogenesis. Detailed molecular analysis of H4K16 isoforms and other posttranslational modified histones has been limited by the lack of means to prepare sufficient material for in vitro study. This paper describes an improved method to prepare acetylated H4K16 as well as other covalently modified histone H4 isoform for biophysical studies.
