A method for systematic mapping of protein lysine methylation identifies functions for HP1β in DNA damage response.
Lysine methylation occurs on both histone and nonhistone proteins. However, our knowledge on the prevalence and function of nonhistone protein methylation is poor. We describe an approach that… Expand
